Andres D'Alessandro - Looked amazing between 2005-2008 but never fulfilled his potential in my opinion.
Ryan Babel that is all
Harry Kewell Thought he would have done better after joining Liverpool but flatered to deceive and always injured.
Davide Bellion Touted as the next Henry, he wasn't even the next Ryan Babel
Kerlon Injuries, Injureis and more Injuries
Christian Wilhelmsson - Looks like a wrold beater for Sweden but some bafflinf transfers (Bolton, Nantes) hindered his progress.
Jose Paolo Guerrero Wasn't a complete flop but didn't live up to the heights he was expected to when he was at Bayern.
Ronaldinho I know he was amazing in his time but 'his time' wasn't long enough. I thought he would be a name thrown around in 'best player ever' conversations, but it isn't.
Podolski Was supposed to be Germany's answer to Rooney but never lived up to the hype. Still great for the national team but quite inconsistent season by season for clubs. Choked at Bayern. Doing okay now though...
Andy van der Meyde The rock and roll lifestyle ruined what seemed to be a VERY promising career.
