Leo Messi scores impressive goal while surrounded by half of Milan

Down 2-0 to Milan after the first leg of their Champions League round of 16 tie, Barcelona needed a comeback that would prove their growing list of doubters wrong and show that they have the gumption to mount a comeback. So Lionel Messi wasted no time in getting his side on the scoresheet in the second leg, pinning a shot to the top corner of the net just five minutes into the match while surrounded by half of Milan's starting XI.

According to Opta this was only Messi's second fastest goal in the Champions League, as he scored in the fourth minute against Basel in 2008.

UPDATE: Messi scored a second goal through Philippe Mexes' legs in the 40th minute to make it 2-2 on aggregate.

UPDATE II: David Villa added a third goal in the 55th minute to put Barcelona up 3-0 in the second leg and 3-2 on aggregate.

UPDATE III: Jordi Alba scored one last goal just before full time to make it 4-0. So how is that "end of an era" for Barcelona going now?
