6) Andrey Arshavin
Although a bit of a late bloomer, Andrey Arshavin looked a sensational talent when he first caught big clubs’ eyes in Euro 2008, putting in some fantastic performances for Russia as they reached the semi-finals of the competition. He then earned his big move to Arsenal, where he started in similarly excellent fashion, including an incredible four-goal haul against Liverpool at Anfield. Slowly, however, he faded into total obscurity and spent his final season at the club barely making the bench before being released.
