Frank Lampard's Chelsea may have already spent more than £200million this summer but the Blues boss is set to strengthen the position that needs improving the most.
Chelsea are set to complete a deal for £25million-rated goalkeeper Edouard Mendy from French side Rennes, according to several reports. The west Londoners are in need of a new shot-stopper following the dip in form of first-choice option Kepa Arrizabalaga and the ageing of back-up Willy Caballero.

The Senegalese international was made first-choice goalkeeper one season later and it proved to be an excellent choice as Reims were promoted to Ligue 1 after they won the French second tier.
After one season in the top flight, Mendy was snapped up by Rennes last summer and represented them in the
