4. Manchester City
Manchester City don't need much, but what they do need is a new centre-back.
With Martin Demichelis struggling with life at the Etihad and Joleon Lescott's future far from certain at the Etihad, Porto defender Eliaquim Mangala could be the ideal signing for Manuel Pellegrini.
Mangala has been extremely impressive in recent time and he would certainly be a hit in Manchester City's team.
