Domestically, Jose Mourinho and Carlo Ancelotti have delivered three Premier League titles for the Russian but it was the relatively unregarded Avram Grant, who having taken over from His Specialness, steered Chelsea to a final against Manchester United, which but for John Terry's pathetic penalty cost the mighty Blues the match.
This year Chelsea have not domestically been the same force to reckon with but in Europe they have been consistent and solid. Blues will now take on ruthless Manchester United in the quarterfinals and Chelsea have every right to believe that they can win against their arch rivals.
Manchester United have not beaten Chelsea at Stamford Bridge since 2002 and Ancelotti's men will be hoping that their good run continued against the Red Devils. Chelsea have already beaten United in Premier League 2-1 and the psychological advantage and can very well work for the Blues.
Chelsea will also have revenge on their mind when they lost to Manchester United in the 2008 finals at Moscow. Chelsea's success has been built on impressive home form and a rock solid defence.
And now they also have a striker Fernando Torres -- who looks bit patchy at the moment but with quality he possesses in him you just can't control that man when he is on song.
A combination of miserly defence and clinical attack is an excellent one to have and is that why Chelsea are hot favourites to finally lift the European Cup this season.
The experienced Ancelotti was brought in by Chelsea owner Roman Abramovich to win the competition and anyone looking to bet on Champions League winner should remember this.
