Graham Potter has been handed two huge blows ahead of Chelsea's blockbuster clash with Arsenal on Sunday afternoon. In the Blues' clash with Dinamo Zagreb, Ben Chilwell pulled up with a hamstring injury and Denis Zakaria was brought off amid a suspected knock.
The latter impressed on his debut for the west Londoners and looked at home alongside Jorginho in midfield. The severity of the Swiss' knock is yet to be revealed but he certainly gave Potter a good headache ahead of the weekend.
N'Golo Kante remains out for some time and Mateo Kovacic is a doubt after missing the final Champions League group stage clash. Edouard Mendy took Kepa Arrizabalaga's place between the sticks against Zagreb after the Spaniard picked up an injury against Brighton.
