1. Bojan Krkic | Ajax
It's hard not to feel sorry for Bojan, who is a lovely lad by all accounts and clearly loved being at Barcelona, where he set records in the youth ranks with his goalscoring exploits.
But he has really struggled at the top level as a senior, which is no real surprise given his slight frame.
His old teammate Lionel Messi is similar in height, but different in his physique. Bojan is far easier to knock off the ball and has lost a lot of confidence in recent years as a result.
Some still see him as the same Bojan who burst onto the scene at the Camp Nou in 2007 – and tip him to enjoy a triumphant return at Barcelona one day - but that player is long gone.
