Chelsea midfielder Mason Mount could make a remarkable comeback from injury to face Liverpool on Sunday.

The 20-year-old, a key figure for boss Frank Lampard so far this season, looked set for a spell on the sidelines after limping off against Valencia on Tuesday night.

Mount was on the end of a late challenge from former Arsenal man Francis Coquelin and replays showed he could have suffered some serious damage.

“He’s a young lad who has come through the academy, the club have worked hard with him, and he has worked hard to get one foot in the first team.

“For me it felt like it was what everyone wanted. I made it clear I wanted him at the club because I believe in his talent.

“Now that a five-year contract is signed it is where the hard work really starts for him.

“He has got everything we are trying to bring, we know the talent he has that he has shown on occasions in the first team when he has had his opportunity.

“I think there is a lot more. It’s pure hard work that will get him there.”
