8: Mario Balotelli to AC Milan
This one makes our list purely because his time at AC Milan has been a complete waste of time. When he left Manchester City Mario Balotelli was a star who had his problems, but was a top European talent all the same.
Since his arrival Milan have done nothing but capitulate and now find themselves out of the Champions League and sitting in a lowly 10th in the Serie A.
A player like Balotelli should never be kept out of the limelight, and we feel plenty of bigger clubs than AC could have afforded to take a punt on him.
