5 of the most exciting Round of 16 ties contested by Chelsea in the Champions League

2) Chelsea vs Barcelona (Agg:- 5-4) 2004/05

Barca's attacking approach at the Camp Nou in the first leg, might have put the game to bed right at the start. However, they failed to capitalize and soon disaster struck as Belleti tried to clear a delightful pass from Damien Duff and put it into his own net.

Didier Drogba soon missed a glorious opportunity and his night went from bad to worse as he was sent off and the tide turned in favour of Barcelona. Frank Rijkaard's side came from behind to win the game 2-1 with goals from Maxi Lopez and Samuel Eto'o.

The return tie at the Bridge was one of the best nights for the Blues as Chelsea scripted an amazing comeback.

Eidur Gudjohnsen lined up to start in place of the suspended Didier Drogba and the move paid dividends immediately. The English side, trailing from the first leg scored 3 goals in the first 19 minutes from Eidur Gudjohnsen, Frank Lampard and Damien Duff to grab the tie by the collar.

When Belleti's cross struck Paulo Ferreira in the arm, Barca were handed a lifeline as Ronaldinho converted the penalty to take the tie to 4-3 on aggregate.Then Ronaldinho showed his class as he outfoxed Petr Cech with a drive from outside the box to shift the balance back in favour of Barcelona. Now Barcelona were in the driving seat with two away goals.

But Chelsea's "Captain, Leader, Legend" John Terry had other ideas as he headed in the ball 14 minutes from time to send Stamford Bridge into a frenzy as the Blues held on to win the tie 5-4 on aggregate.
