4. Abdul Baba Rahman
The Ghanaian was signed with a lot of fanfare and a huge check by Jose Mourinho from Augsburg but the 21-year-old just hasn’t had the impact that he would have liked in the Premier League. Baba has had chances to show what he is capable of but unfortunately for the ex-Bundesliga star it just isn’t working for him in England. The 21-year-old could well be looking for a move back to Germany where he excelled as it seems that his time at Chelsea hasn’t been the greatest for him.
