7. Messi vs Arsenal (2011)
http://youtu.be/N42dkvKrSj8 Arsenal have been on the receiving end of a number of memorable Messi displays, and this goal in a Champions League clash back in 2010/11 was sheer genius. Cesc Fabregas surrendered possession for the Gunners in a dangerous area of the pitch, and after Andres Iniesta found Messi following a typically mazy run, he impudently flicked the ball over the dive of Wojciech Szczesny and fired the ball into the empty net. Not many players in the history of the game are capable of such quick-thinking, but Messi is undoubtedly one of them.
