Wilshere makes Arsenal return after long-term absence

(CNN) -- England and Arsenal midfielder Jack Wilshere looks set to finally end his nightmare year after making a return to first-team training.

The 20-year-old missed the entire of last season after suffering an ankle injury during a pre-season friendly in August 2011.

He then suffered a setback earlier this year and was forced to undergo surgery on his knee in May.

Wilshere's agent, Si Bayliff, tweeted: "Delighted to say that Jack Wilshere was back in full 1st team training today.

"Understandably he is a very excited young man."

In 2009, Robert Enke was first-choice goalkeeper for the German national football team, enjoying a successful club spell with Hannover. But in November of that year, he took his own life by stepping in front of train. The 32-year-old had been battling depression for the majority of his career and the story of his struggle is told movingly in Ronald Reng's acclaimed biography "A life too short: The tragedy of Robert Enke".

Kelly Holmes is a British sporting hero after winning her gold medals over 800 and 1500 meters at the Athens 2004 Olympic Games. But the track star has had to fight depression throughout her life, including a period of self-harming in the year before her Olympic triumph.

Stan Collymore is former England footballer turned broadcaster who now campaigns for depression charities. He tweeted last year: "I'm tweeting because the stigma around this illness suggests that us sufferers all of a sudden become useless, maudlin, and unable to function. Well, I haven't seen daylight for 4 days now ... but I've done a week of Talksport/Channel 5 prep work, a national newspaper column, all in the eye of one of the most challenging, soul destroying bouts of this cruel illness one could have."

Sebastian Diesler was hailed as the future of German football after bursting onto the international scene at the start of the last decade. His performances earned him a move to Bayern Munich in 2002, but by 2007 he had retired -- aged 27. Diesler endured an injury-ravaged career, while struggling to come to terms with the pressure of professional football.

Boxer Ricky Hatton revealed he contemplated suicide following his brutal defeat to Manny Pacquiao in 2009. Hatton, who has suffered from drink and drug problems, retired from the sport in the aftermath of the loss, but this month announced he intends to make a return to the ring in November.

Marcus Trescothick was a key member of the England Test cricket team which beat Australia to win the Ashes in 2005. Ahead of the return series in 2007, England announced Trescothick would be leaving the squad citing a reccurence of a stress-related illness as the reason.

Jerry West is an NBA icon who revealed he has been battling depression since childhood, stemming from his abusive father. West said his relationship with his father left him feeling worthless and tormented.

Former New Zealand rugby international John Kirwan spoke in detail about his battle with depression in the book "All Blacks Don't Cry". He is actively involved with mental health campaigns in his homeland.

Sport's battle against depression

From Inter Milan to Manchester City: The reigning English Premier League champions have snapped up right-back Maicon for an undisclosed fee to help boost their bid for domestic and European honors in 2013. The Brazilian international has been at the San Siro for the past six seasons and made 235 appearances for the club.

Spurs to Hamburg: The Dutch international returns to the Bundesliga after a successful two-year spell at the north London club. Van der Vaart played for Hamburg from 2005 to 2008 before joining Spanish champions Real Madrid.

Manchester United to Fulham: With the arrival of Robin van Persie from Arsenal earlier this month, the chances of Dimitar Berbatov playing even more of a bit part at Old Trafford have only increased. Fulham have been the benefactors of Alex Ferguson's growing indifference to the player he signed for $47 million from Tottenham Hotspur in 2008. The 31-year-old Bulgarian rejected suitors in Italy, notably Juventus and Fiorentina, to stay in the English Premier League.

Sao Paulo to Paris Saint-Germain

The $55 million paid by PSG for 19-year-old midfielder Lucas Moura broke the Brazilian transfer record for the third time this year, eclipsing the fee the French club spent on Thiago Silva and Chelsea's deal for Oscar. He will move to Paris in January, becoming the sixth Brazilian at the club.

AC Milan to Paris Saint-Germain

At $50.75 million, Thiago Silva is the world's most expensive defender in terms of upfront transfer fees -- though the largest including add-ons remains Rio Ferdinand's move from Leeds to Manchester United, which eventually rose to $150,000 more than the Brazilian's total). The 27-year-old spent three years in Italy with AC Milan and is an established international.

Athletic Bilbao to Bayern Munich

Spain midfielder Javi Martinez completed a "complicated" move to the Bundesliga giants after activating a $50 million buyout clause in his contract that left him having to foot some of the bill.

Tottenham to Real Madrid

Luka Modric completed his long-awaited switch from English club Tottenham Hotspur to Spanish champions Real Madrid for a reported $50 million. After attempting to force a transfer ahead of the 2011-12 season, the Croatian has finally got his move away from White Hart Lane.

Lille to Chelsea

Eyebrows may have been raised upon seeing the size of the $49.5 million transfer fee Chelsea paid for Eden Hazard, but the 21-year-old Belgium winger is one of Europe's biggest talents, having being selected for the Ligue 1 Team of the Year three times in a row.

Internacional to Chelsea

After a protracted saga of a transfer, Chelsea finally gave in to Internacional president Giovanni Luigi's demands and paid a Brazilian transfer record $39.25 million for 20-year-old midfielder Oscar. Only time will tell if the talented young playmaker is worth the money, but with so many creative options at Roberto di Matteo's disposal he may well have to make an immediate impact or risk spending a season on the bench.

Arsenal to Manchester United

Robin van Persie, the English Premier League's top scorer last season, stunned Arsenal fans by joining rivals United for $37 million after refusing to sign a new contract.

Napoli to Paris Saint-Germain

Argentina international forward Ezequiel Lavezzi arrives at PSG with a $36.25 million price tag and a big reputation following his five years in Italy. He will link up with another former Serie A star in Zlatan Ibrahimovic.

Borussia Dortmund to Manchester United

Those who cynically write off $26.25 million signing Shinji Kagawa as nothing more than a ploy to boost United shirt sales in Asia do so at their own peril -- the 23-year-old is a top-level player with excellent credentials: two Bundesliga titles, one German Cup, an Asian Cup and more than 30 appearances for Japan.

Everton to Manchester City

Young England international Jack Rodwell was Roberto Mancini's first signing since winning Manchester City's first English league title in 43 years. At $24 million he is far from the most expensive player at the Etihad Stadium, but the highly-rated 21-year-old midfielder is seen as a long-term investment.

AC Milan to Paris Saint-Germain

Until last season, Zlatan Ibrahimovic had won the league eight years in a row with five different clubs. The Sweden striker's $24 million move to PSG pushed him further ahead of Nicolas Anelka as the most expensive player of all time, with total transfers of more than $210 million.

Arsenal to Barcelona

For the second year in a row, a key Arsenal player has been lured to Spain by Barcelona. Last August it was Cesc Fabregas, this time it's Cameroon midfielder Alex Song. The 25-year-old moved for $23.7 million on a five-year contract, with a release clause of $100 million.

Malaga to Arsenal

Spain star Santi Cazorla was one of Malaga's marquee signings last season, but is the first of the troubled Spanish club's high-profile players to depart in the midst of financial problems. The winger's $23.5 million fee is similar what he cost when joining from Villarreal.

Borussia Monchengladbach to Borussia Dortmund

Finishing fourth in both goals scored and assists last season, Marco Reus almost single-handedly pushed Borussia Monchengladbach to a fourth-place finish in Germany and Champions League football. Champions Dortmund see the 23-year-old, who cost $21 million, as the ideal replacement for Shinji Kagawa -- and if his brief appearances at Euro 2012 are anything to go by he could become much more.

FC Twente to Borussia Monchengladbach

After much interest from all corners of Europe, FC Twente's top-scoring target man Luuk de Jong decided to join Borussia Monchengladbach in an $18. 5 million deal. The 21-year-old, who scored 25 goals in 32 appearances last season, went to Euro 2012 but did not appear for the Netherlands.

Montpellier to Arsenal

With the eyes of the English Premier League's fans firmly set on the Robin Van Persie transfer saga, many have neglected the man coming in to replace him -- $18.5 million France international Olivier Giroud. For all the money PSG spent last season, it was Giroud and his 21 goals which spurred underdogs Montpellier to a first Ligue 1 title.

Valencia to Barcelona

New Barca boss Tito Villanova acted quickly to fill the gap left since Eric Abidal's liver transplant, bringing in Spain's Euro 2012 surprise standout player Jordi Alba for a bargain $17 million to fill the left-back slot before the tournament had even finished.

AS Roma to Liverpool

New Liverpool boss Brendan Rodgers paid $17 million for 21-year-old striker Fabio Borini, whose nine goals in 24 appearances at Roma earned him selection for Italy's Euro 2012 squad. He returns to Britain following an earlier loan spell with Rodgers' former club Swansea.

FC Cologne to Arsenal

Lukas Podolski has left his childhood club Cologne for the second time, having struggled to make an impression at Bayern Munich following his 2006 transfer. The Germany star cost Arsenal $15.75 million after scoring 18 Bundesliga goals last season -- which was not enough for "the Billy Goats" to avoid relegation.

Vfl Wolfsburg to Bayern Munich

A surprise star of Euro 2012, Mario Mandzukic scored three times in three games for Croatia to be the tournament's equal top scorer. Bayern paid Bundesliga rivals Wolfsburg $15.75 million for the 26-year-old striker's services.

Ajax to Tottenham Hotspur

Belgium international Jan Vertonghen is already being touted by Tottenham fans as the long-term replacement for injury-plagued former captain Ledley King in the center of defense. His protracted $11.5 million transfer could prove key to the fortunes of new Spurs boss Andre-Villas Boas.

Marseille to Chelsea

Chelsea took its spending in the current transfer window to over $100m with the signing of Spanish full back Cesar Azpilicueta from French team Marseille.

Werder Bremen to Chelsea

Germany midfielder Marko Marin agreed his $9.5 million move to Chelsea before last season had even finished, and the 23-year-old is expected to make a big impact for the European champions with the skills that have seen him dubbed "the German Messi."

AC Milan to Internazionale

Antonio Cassano has left AC Milan to join city rivals Inter, while fellow Italy striker Giampaolo Pazzini went in the other direction. Milan had to pay a reported $8.7 million extra for Pazzini, who at 28 is two years younger than his former Sampdoria teammate. Cassano, meanwhile, recovered from heart surgery to help Italy reach the final of Euro 2012.

Internazionale to Internacional

Diego Forlan struggled to impress in his one season in Italy after seven prolific years in Spain's top flight, but the 33-year-old Uruguay striker could prove to be a free-transfer bargain in Brazil for Internacional. He was named best player at the 2010 World Cup, where he was joint top scorer, and has led the goal charts twice in Europe.

Fiorentina to AC Milan

Midfielder Riccardo Montolivo agreed to join Milan on a free transfer before helping Italy reach the final of Euro 2012, having spent seven years at Fiorentina.

Real Madrid to Liverpool

Turkey midfielder Nuri Sahin failed to impress in in his one season at Real Madrid after being snapped up from German champions Borussia Dortmund, and has been given the chance to kickstart his career in the English Premier League.

Top European football transfers

Footballers' salaries surge

However, Arsenal manager Arsene Wenger is unlikely to rush Wilshere back into action immediately with his side enjoying an impressive start to the season.

Spain winger Cazorla joins Arsenal from Malaga

The Gunners sit third in the Premier League after four games and defeated French champions Montpellier in their opening Champions League fixture on Tuesday.

Wilshere is instead expected to play for the club's Under-21 side against West Bromwich Albion on October 1 or against Reading a week later.

"It's been 14 months and that's a long time for someone at his age," Wenger told the club's official website.

"It's an eternity, but it's great news. We have to give him a few training sessions to see how he copes and responds to it.

"That's the delicate, sensitive stage -- to choose when to bring him in and out. We'll have to handle that day by day."

Arsenal has also been encouraged by the news that Emmanuel Frimpong has returned to training after recovering from an anterior cruciate knee ligament injury he picked up during last season's loan spell at Wolves.

Wenger said: "We also have Emmanuel Frimpong who has returned to full training this week, which is great news as well.

"Emmanuel has also been out a long time, but is progressing well."
