Chelsea midfielder Mason Mount has "a chance" of recovering from his ankle injury in time to face Liverpool in the Premier League on Sunday, according to head coach Frank Lampard.
Mount, who has scored three goals in Chelsea's opening five league games, was forced off early in Tuesday's Champions League defeat to Valencia following a reckless challenge by former Arsenal midfielder Francis Coquelin.

Despite initial fears over potential ligament damage, the 20-year-old has made a swift recovery and could now face the Premier League leaders at Stamford Bridge on Sunday, live on Sky Sports.
"He's got a chance," Lampard said. "The image of the tackle afterwards made it look really bad, but hopefully it's not so bad.
"We're trying to get him moving today and it's one I'll have to call just before the game with another 24 hours in the bank.
"The good thing with Mason is his attitude is so good that he'll give everything to get out there and play for this club, particularly in a game of this size."
Chelsea could welcome back another crucial central midfielder for Sunday's game, with N'Golo Kante having returned to training after missing four games with a sprained ankle.
The Frenchman impressed in Chelsea's UEFA Super Cup defeat to Liverpool in August when he was considered a major doubt for the game, but Lampard isn't counting on a repeat this time around.
"It's a boost with N'Golo," Lampard said. "We all know the importance of him for the team with the attributes that he brings.
"The only question for me is how fit he is because he's had a long time out now since the back end of last season.
"I know he played a couple of games this year but I didn't count them as such because he missed the pre-season and what he did in Istanbul was miraculous as opposed to the norm, to play how he did without training."
