Chelsea lost a heartbreaker in the 93rd minute due to a fabulous Iniesta strike. The aggregate was 1-1 but the away goal advantage applied in Barca's case and they will meet Man Utd in the final on May 27.
Michael Essien was involved in both goals.
The equalizer would not have been possible if Essien had not whiffed on Samuel Eto'o's heavy first touch, helping the ball along to Messi who collected and side passed to Iniesta who lined up and cracked the ball past all that heavy traffic and over Cech. It was Essien however, who came out of nowhere with an amazing volley that got Chelsea the goal which brought them so close, so tantalizingly close to their second consecutive CL final.
