Chelsea have agreed a deal with Rennes to sign goalkeeper Edouard Mendy.
The Senegalese international, 28, is wanted by manager Frank Lampard to increase competition with club record £71m signing Kepa Arrizabalaga.
Kepa was at fault for Liverpool’s second goal in the 2-0 Premier League defeat on Sunday, which was described as “a clear mistake” by Lampard.
The Spanish international was also dropped last season after errors in games.
That included the FA Cup final, where the 25-year-old was replaced by second-choice goalkeeper Willy Caballero, who is 38.
Following the defeat at home to champions Liverpool, Lampard said Caballero would start the Carabao Cup tie against Barnsley at Stamford Bridge on Wednesday.
