Chelsea moved back into fourth position in the Premier League table after a 3-0 victory over Watford at Stamford Bridge on Saturday.
Chelsea midfielder N’Golo Kante was replaced by Billy Gilmour in the second half after he picked up an injury.
Chelsea boss Frank Lampard has revealed the Frenchman picked up a hamstring injury against Watford.
“He’s got a small hamstring injury so we will see how that goes,” he said.
“Hopefully it is not too bad but it comes with the territory of this tight restart and tight run of games.
“A lack of pre-season and we have to rely on the squad. There will be players that come in and can perform for us as well. But it is the same for everybody.”
