#3 Mario Balotelli
The former AC Milan striker initially joined Manchester City, where he had disciplinary problems and was constantly in the news for his on-field and off-field incidents.
He again made a return to the premier league with Liverpool but failed to make a mark at Liverpool and returned to Milan on loan next season.
Since his move to the French outfit - Nice, Mario Balotelli has revived his career.In 31 appearances he has scored 22 goals for the club. Recently Nice's President revealed that without European football, they might not be able to keep hold of the Italian.
Balotelli would be a good fit for Chelsea considering his past Premier League experience and his age of just 27. Also, Balotelli will be out of contract next season and will be relatively easy to poach.
There is no doubt that Balotelli is a quality player and now he seems to have become a matured player as well. During his time in Manchester, he has shown that when at his best it is very difficult to stop him.
