West Ham are thought to be keeping tabs on the La Liga centre back Diego Llorente.
According to Mundo Deportivo, they are keen on the player who has a release clause of around €50m. Spurs and Liverpool are keen on the player as well.
Manuel Pellegrini needs to improve his back four and Llorente would be a superb addition. Issa Diop is the best defender at the club and he needs a solid partner alongside him.
Reid and Balbuena are decent players but Llorente would be an upgrade on them.
