“Chelsea have agreed personal terms with Mendy few days ago – new bid expected soon to complete the agreement with Rennes,” he wrote.
“Deal still expected to be done soon. No chances for Oblak as always said.”
Chelsea wanted to sell Arrizabalaga but there are now buyers after his signature, so he will fight for his place in the squad.
Mendy will likely be the seventh signing of Chelsea’s window, after bringing in Timo Werner, Hakim Ziyech, Malang Sarr, Ben Chilwell, Thiago Silva and Kai Havertz.
