English Premier League clubs have spent more than £1 billion ($1.4 billion) on transfers in a season for the first time, new figures from Deloitte reveal.
The last day of Europe's January transfer window -- this year it was February 1 -- is usually very hectic, but Monday's announcement that Pep Guardiola will take over from Manuel Pellegrini as Manchester City manager at the end of the 2015-16 season arguably trumped any of the player moves.

China's transfer window is open until February 26 -- which allowed Guangzhou Evergrande to smash the country's record fee by splashing out on the Colombia forward. The 29-year-old had struggled in Spain after his $38 million move in July 2015 from Porto, where he was a prolific goalscorer in three seasons with the Portuguese team.

The Brazilian's deal shattered the Chinese transfer record. During his time at Stamford Bridge, Ramires made 251 appearances, scoring 34 goals, helping the club to win the English Premier League, FA Cup, League Cup, UEFA Champions League and Europa League. The dynamic midfielder will join up with former Blues defender Dan Petrescu, who manages Jiangsu Suning.

Still just 26, Pato was once the most exciting Brazilian wonderkid on the conveyor belt, but his initial promise has been marred by a succession of injuries. Chelsea fans will hope the former AC Milan striker can replicate the form that netted him 10 goals in 27 international appearances -- though they could be forgiven for worrying he will repeat the struggles of Radamel Falcao at Stamford Bridge.

The 23-year-old, seeking to win back his Italy place ahead of Euro 2016, returned to Serie A on a $2 million loan deal with an option to join Roma permanently for a further fee of $14.2 million.

Precociously talented, naggingly inconsistent, the 23-year-old England international has switched Premier League teams with his best years ahead of him, but opinion divided. He initially impressed at the Welsh club following his 2013 move from Liverpool, but was a peripheral figure in midfield this season. Matthew Lewis/Getty Images Europe/Getty Images

The dynamic Ivory Coast international will hope to end struggling Newcastle's search for a top goalscorer. Though he was loaned back to CSKA Moscow after failing to impress in Serie A, his record in Russia -- 66 goals in 108 league games over two spells -- shows his pedigree. Doumbia's career goals-per-game ratio in the Champions League -- netting 16 times in 22 matches -- puts him up there with greats like Gerd Müller, Ferenc Puskás, Lionel Messi and Eusébio in Europe's top club competition.

Crystal Palace signed a player with undoubted Premier League pedigree, albeit one who hasn't quite lived up to his promise.

The former England U21 international boosts the striking options of Eddie Howe's Bournemouth side, after the impressive Callum Wilson was ruled out with a cruciate ligament injury in September.

The latest in a long line of touted heirs to Lionel Messi's footballing throne, the diminutive Argentine winger moved from Hellas Verona to Roma for $25 million in 2014. Having been largely used as a substitute by the Serie A side in recent months, the 22-year-old arrived at the English Premier League club with a point to prove.

The 28-year-old played at top clubs such as PSV Eindhoven and Galatasaray before moving to Malaga in Spain and now Watford, one of the surprise teams in the English Premier League.

The Scotland forward scored 25 goals in 123 appearances for the Toffees -- including a memorable hat-trick against José Mourinho's Chelsea this season.

The 23-year-old midfielder put pen to paper on a five-and-a-half year contract, having only joined Porto seven months ago from Marseille.

The Dutch international midfielder joined the Swans on deadline day from Championship club, QPR. Fer has previously played for Norwich City, as well as Eredivisie sides FC Twente and Feyenoord.

Everton moved to replace the departing Steven Naismith with Senegal forward Oumar Niasse. Niasse, 25, scored 13 in 23 appearances this season before the move, and was enthused by the prospect of playing under the Everton manager, Roberto Martinez. "I was interested to see how they play," said Niasse. "If you see players who are aged 20 or 21 and see them perform like that, you know you have a good coach."
