Liverpool boss Jurgen Klopp had no problem with Alex Oxlade-Chamberlain's fury on Sunday.

Klopp has downplayed Oxlade-Chamberlain's angry reaction to being substituted in Liverpool's 2-0 victory against Manchester United on Sunday.

Oxlade-Chamberlain was replaced by Adam Lallana in the 66th minute at Anfield and was visibly unhappy to leave the pitch. He smacked the back of a seat in the dugout as he joined the other substitutes.

"He is not frustrated, he just looks like this," Klopp said in his pre-match press conference ahead of Thursday's Premier League encounter against Wolves. "I asked him and it is fine.

"It is normal a player wants to play 90 minutes but we have to learn from our own past. Oxlade is an unbelievably important player for us.

"There are moments in a game where players get a bit tired and they show up. I try to read the players during a game and try to understand which moment they are, energy level-wise, and make a decision.

"Sometimes I hit the point and sometimes not, maybe with Ox last time I was a bit too early but he got a knock on top of that. He was limping a little bit.

"If a midfielder is limping you start looking in detail and sometimes in a defensive situation, a midfielder is not where he should be and then there is the impact. You have to make a decision. After the game it didn't feel that bad, the knock he got."
