#3 Arsenal (8/3/2011)
Arsene Wenger’s side has the dubious distinction of being Messi’s favourite opponent in Europe – he has scored against them on four separate occasions. A year after his four-goal haul at Camp Nou, he scored another vital goal against the Emirates outfit – this one of arguably even greater quality.
Beaten 2-1 in the first leg away from home and struggling to make an impression in the second, the tie was blown open in first-half stoppage time. Andres Iniesta was the man to make the incursion this time, clipping a deft pass through for the No.10. With almost no room to work, he lifted the ball impossibly over the head of Almunia before turning the ball into an empty goal.
Barca turned the tie around, with Messi getting the winner with 18 minutes left, of course.
