(CNN) -- What started out as Chelsea's worst season since owner Roman Abramovich arrived in 2003 is now on the verge of becoming one of the English club's best.
Saturday's FA Cup final success, the London side's fourth in six years in the world's oldest football competition, is the latest step in a revival that could end in the realization of the Russian billionaire's longheld dream.
The nailbiting 2-1 victory at Wembley is but a tasty precursor to a Champions League final in Munich on May 19 that offers the chance for Abramovich to finally win Europe's top club prize.
He brought Premier League success to Stamford Bridge in 2005 after spending millions on coach Jose Mourinho and a swathe of star players, achieving Chelsea's first English title in 50 years.
Two more followed, but not before Mourinho departed after failing to repeat the European triumph at Porto that earned Abramovich's attention -- and Avram Grant, Luiz Felipe Scolari and Carlo Ancelotti also exited as Champions League success proved elusive.
Andre Villas-Boas, "the new Mourinho," was bought out of his contract at Porto to replace Ancelotti -- a European champion as both player and coach -- but the Portuguese prodigy alienated Chelsea's powerful old guard of players as he sought to stamp his authority and rebuild the squad.
His assistant Roberto di Matteo, a former Chelsea player himself, has had no such problems winning their respect as he has reverted to the style so successful under Mourinho, allowing the likes of veterans Frank Lampard and Didier Drogba to restore their pre-eminent roles in the team.
Drogba scored the vital winner in the first leg of the remarkable Champions League semifinal success against arguably the world's best team, Barcelona, and he netted the ultimately decisive second goal against Liverpool.
The 34-year-old Ivory Coast captain is now the only player to score in four FA Cup finals, equaling the five goals in total scored by legendary Liverpool striker Ian Rush in three title matches.
Drogba may yet make his Chelsea exit after the Bayern Munich clash in two weeks' time -- a match which not only holds the key to Abramovich's hopes, but could also be part of a solution to the challenges the club faces under European soccer's new financial fair play rules.
Each team will get a reported $66 million for making the final, when television money is added to the prize total on offer, representing a major budgetary boost for a club like Chelsea -- which under the new regulations can no longer rely on Abramovich's deep pockets.
Chelsea's bid to become more financially self-sufficient took another step ahead of Saturday's final, with news the club is seeking to buy the nearby iconic Battersea power station and turn it into a new home ground with capacity greater than the present one.
The $2.9 million earned by winning the FA Cup final for the seventh time will also help, as well as furthering the prospects of Di Matteo being made Chelsea's permanent manager.
Brazil midfielder Ramires followed up his second-leg goal against Barcelona with the opening strike in the 11th minute as he beat goalkeeper Pepe Reina at the near post with a low shot.
Drogba doubled the lead seven minutes after halftime, but Liverpool substitute Andy Carroll ensured a nervy finish after reducing the deficit on 64.
The striker -- who has struggled since joining Liverpool for a club-record $50 million fee in January 2011 after Fernando Torres left for Chelsea for $30 million more than that -- thought he had leveled the scores with a late header.
However, Chelsea keeper Petr Cech clawed the ball clear off the underside of the crossbar apparently before it had crossed the line -- much to the disgust of Liverpool striker Luis Suarez, who was booked for remonstrating with the line official.
"We've been heavily criticised this season and we've got a trophy and we've got the chance for another," said Di Matteo, who scored in two FA Cup final wins for Chelsea in 1997 and 2000.
"This group of players have made the club proud. It's been hard work, but we came through it."
Liverpool will play in Europe next season, albeit the second-tier Europa League after winning the League Cup in February, but it has been an otherwise disappointing season under manager Kenny Dalglish.
The 18-time English champions trail sixth-placed Chelsea by 12 points with two games to play in the Premier League, a situation which cannot please the club's American owners -- who are looking to emulate the success they have had with baseball's Boston Red Sox.
"They were better than us for the first hour," Dalglish said after the final. "We finished really strong and if we'd started the way we'd finished we'd maybe have been happier than we are now. We've just got to learn the lessons."
Abramovich's hopes of Champions League football next season, meanwhile, appear to rest solely on victory in Munich, despite a slip-up by third-placed London rivals Arsenal on Saturday.
Arsenal's 3-3 draw with Norwich gave Tottenham and Newcastle the chance to move up to third and fourth with victories on Sunday.
Spurs, who hold the edge on goal difference only, face relegation-threatened Aston Villa while the in-form Magpies will seek to follow up Wednesday's 2-0 win over Chelsea with another result against league leaders Manchester City.
Both clubs are five points clear of Chelsea, but know that the fourth-placed team will be bumped down to the Europa League if Abramovich gets what he really wants in Germany.
City returned to the top on goal difference with a 1-0 win in Monday's Manchester derby, but second-placed local rivals United have easier opposition on Sunday as the defending champions host mid-table Swansea.
