19. Adnan Januzaj – Manchester United to Manchester City
The young Belgian winger has been tipped to make a big impact with the defending champions, but still, when you’re not playing and growing frustrated at not being allowed to show what you can do and another club comes in for you – it’s easy to have your head turned. Januzaj is already being linked with Manchester City and as he is now in the final year of his contract with David Moyes’ men he will be able to negotiate a deal with someone else and sign on from January.
