Liverpool striker Sadio Mane suffered a dead leg in his side’s 2-1 win at Chelsea, boss Jurgen Klopp confirmed.
The in-form frontman, who has scored six goals this season, hobbled off in the second half at Stamford Bridge on Sunday with the problem, which was two-fold.
“It was a knock on the bone, around the knee, and a dead leg - that’s an awful combination,” Klopp said.
“He tried everything but I think you saw, there was one counter situation when he really tried and I would say on a non-dead-leg day he will get that ball, but no chance.
“And then we say ‘Come on, now we have to do it’ and changed. That’s it.”
Goals from Trent Alexander-Arnold and Roberto Firmino earned Liverpool a 15th Premier League win on the bounce and restored their five-point lead over Manchester City.
Alexander-Arnold’s opener was superb as he fired a free-kick into the top corner from the edge of the area for his first goal since November last year.
“Hendo (Jordan Henderson) wanted it at first and then I think he thought it was a bit too close for him,” Alexander-Arnold told Sky Sports.
“I discussed with Mo (Salah) that I wanted it rolled to make the angle a little bit better and maybe confuse the goalkeeper a little bit, and I’ve been able to put it away.
“I thought it was too close to go over the wall, I didn’t know if the wall was going to jump so I couldn’t go under it, I had to go ‘keeper’s side.
“It was a good roll and I just tried to put it as hard as I can that side with a bit of placement.”
Chelsea put up a fight in the second half, scoring through N’Golo Kante’s fine individual strike, but just fell short.
Their chances were hampered by injuries to Emerson and Andreas Christensen in the first half, meaning two substitutions on defensive changes were used up early.
Meanwhile, Klopp has been named men’s coach of the year at the Best FIFA awards in Milan.
Klopp guided his side to Champions League glory last season, while the Reds narrowly missed out on the Premier League title, being pipped by Manchester City.
The German claimed the award ahead of Tottenham boss Mauricio Pochettino, whose team Liverpool defeated in the Champions League final, and City’s Pep Guardiola.
Klopp said at the ceremony at Milan’s Teatro all Scala: “Mauricio - we won that game, that’s why I’m here, not you. That’s how football is, but we all know what an incredible job you did, what an incredible job Pep did, what so many coaches out there did.
“I have to say thank you to my outstanding club, Liverpool FC, to the owners, I have to say they gave me an incredible team, and I have to thank my team, because as a coach you only can be as good as your team is.”
“I’m really proud of being the manager of such an incredible bunch of players.”
Klopp took the opportunity to reveal he had signed up to the Common Goal movement, in which members donate one per cent of their salary to a charity which funds organisations around the world that use football to tackle social issues.
He said: “I’m really proud and happy that I can announce that from today on I am a member of the Common Goal family.”
Having then received a round of applause, Klopp said: “A few people obviously know it - if not, Google it. It's a great thing.”
