Jose Mourinho has hinted at his frustration with Chelsea's medical department as the Blues boss waits on the return of John Terry.
• Worrall: City give Chelsea the blues
Terry, 33, has missed Chelsea's last three matches with a muscle injury, and Mourinho's men have won only one of those fixtures during that time.
The centre-back has been in impressive form for the Blues this campaign and his manager is hopeful he will have him at his disposal for their Premier League match against Everton this weekend.
"The medical department always tell me he looks like he is ready," Mourinho said in the Daily Mirror.
"I was told he would probably play this game. He didn't, so now do they say for sure he plays the next game? I don't know."
Meanwhile, Mourinho has suggested Manchester City are at an advantage by playing after their title rivals, following the change in fixture times in light of their League Cup final with Sunderland and the rearranged league meeting with the Black Cats.
"What affects the Premier League is the change of the fixtures,” he said. "City play later after the other teams fighting for the title play, so it is easier.
"They know somebody lost, somebody won, they lost two points, one point is enough for us. That is obviously an advantage.
"But it’s not their fault. It’s the weather, the fixtures, the FA, the Premier League, so it’s not their fault."
