Despite the January transfer window closing last Friday, the rumours and speculations will naturally continue.

Chelsea fans were left disappointed with their clubs transfer business during January, having failed to bring in a single player and leaving manager Frank Lampard visibly frustrated.

Some of the more optimistic supporters believe that any of The Blues main business has been saved for the summer, with the winter window being notoriously more difficult to bring players in.

Investment and somewhat of a squad overhaul is badly needed at Stamford Bridge, and Lampard needs to be backed with his targets.

One player who he might be looking at is Napoli’s experienced centre back Kalidou Koulibaly.

A player who has often been mentioned with a move to Chelsea, and is exactly what they need in the heart of their defence in terms of experience and leadership.

The Sun have ran a story today suggesting that Manchester United will launch a £90 million move for Koulibaly in the summer, but face stiff competition from Chelsea who they claim are also keen on signing him.
