The 27-year-old midfielder played the full 90 minutes and picked up a yellow card as Liverpool FC claimed a goalless draw with FC Porto at Anfield on Tuesday night to book their place in the quarter-finals of the Champions League.
The England midfielder appeared to be struggling with some sort of injury during the game, but Klopp has insisted that the problem is not serious as the Reds prepare for their crunch trip to Old Trafford.
Speaking at his post-match news conference on Tuesday, Klopp said: “It was a dead leg. ‘Just’ I don’t know – it’s painful enough but it’s a dead leg and should not be a problem.”
Liverpool FC turn their attentions towards their crunch clash with Manchester United on Saturday afternoon.
Klopp’s men head into the game knowing that a victory would move them up into second place in the Premier League table and above Manchester United with eight games left to play.
The German manager has been charged with steering the Reds to another top four finish this season after the Merseyside outfit ended up in fourth place in the table last term.
Liverpool FC are yet to win a trophy under Klopp since his appointment in October 2015.
