Liverpool boss Jurgen Klopp has told Marko Grujic to control himself after committing horror tackles on Crystal Palace duo James Tomkins and Wilfried Zaha.

Tomkins branded Grujic’s tackle “disgusting” after the Serb injured the former West Ham man in April.

And Eagles boss Frank de Boer hit out at the 21-year-old following a nasty challenge on Zaha in a pre-season game in Hong Kong.

Grujic featured just eight times for the Reds last season, and picked up three yellow cards.

And Klopp says his aggressive playing style has to change.

He told the Liverpool Echo: “I didn’t see it properly at the time but I heard it could have been a red card [for the foul on Zaha].

“That’s not good. For Marko, it’s something that he has to change.

“He’s a fantastic player, a really skilled boy. Tall, quick, talented footballing wise, all good.

“But in these defensive situations, you always need to be early so you are close enough to make a challenge and not a foul.

“It’s about coming too late, switching off the machine, trying to sort a situation in which you were late in mind. I hate that.

“When that happens you need to run, not foul. Make more steps, go, go, go. For me, it’s always a bit lazy.”
