Eliaquim Mangala (FC Porto)
Young French centre-back has been rock solid over the course of the past two seasons, helping his FC Porto side to back to back Primeira Liga titles.
With FC Porto struggling to retain the title this term there is every chance the 22 year old would look to leave in pursuit of a high profile move.
With both Rio Ferdinand and Nemanja Vidic set to leave Old Trafford David Moyes is certainly in the market for a fresh central defensive purchase.
