Top 5 nights in Chelsea's Champions League history

#2 Barcelona 2-2 Chelsea (Semi-final 2nd leg, 2011-12)

Torres scored a memorable goal at the Camp Nou

Chelsea held a slender 1-0 advantage going into this tie. But the aura of the Camp Nou and Pep Guardiola's brilliant team meant that the job was far from done.

Barcelona dominated possession and the game from the first minute and Sergio Busquets slotted home to level the tie. Chelsea's night worsened as Gary Cahill limped off and their skipper Terry was sent off for elbowing Alexis Sanchez. Soon after that, Iniesta scored and a rout looked on cards for the 10-men Blues.

However, Ramires sumptuously chipped Victor Valdes to give his side a foothold in the game. That unexpected goal had put Chelsea ahead by the away goal rule. But the Catalans had 45 minutes to test the Chelsea goal and knock them out.

The chances came, and they did not stop. But Chelsea repelled everything, almost as if Terry's departure had added more steel. Ivanovic blocked Iniesta heroically. Sanchez missed a sitter. Messi struck the bar with a penalty. Sanchez had a goal ruled out for offside. Cech pulled off a blinder of a save from Messi. But Chelsea did not wilt under the mounting pressure. They repelled and repelled until...

...until from nowhere Fernando Torres was set free on goal and he completed the unthinkable (Gary Neville did the unbearable).

Chelsea, devoid of their two centre-backs and playing with 10 men, with less than 25% possession had defeated the unrivalled greatest team then, European champions Barcelona in their backyard to book a place in the Champions League final. Some night.
