4- Eliaquim Mangala

The 22-year-old Porto defender is one of the most sought after properties in Europe, with Manchester City in particular highlighting their intent to sign him.

Porto managed to keep hold of him over the summer and may offer him a new deal in a bid to keep him away from the clutches of the Premier League signs who will compete to acquire him, but if he has ambition to match his talent then he may leave nonetheless. 

With defensive woes and injuries aplenty, Pellegrini may see no option but to move for Mangala in January.
