Jurgen Klopp warned by the police over his touchline behaviour

Jurgen Klopp has been told to calm down by police.

The excitable Liverpool manager was warned about his behaviour during last night's 1-0 win away to Sunderland, according to The Guardian. Klopp was unhappy with a tackle by Black Cats player Jeremain Lens on Mamadou Sakho. The Dutch winger landed an awkward looking tackle on the Liverpool defender in the second half, receiving a yellow card. However, Klopp felt it should've been red and became involved in an touchline argument with Sunderland manager Sam Allardyce.Allardyce said Klopp used "foul and abusive language", and the Liverpool manager is a "soft German" if he thought the challenge merited a red card. The pair shook hands at the final whistle, but Klopp made no apologises about the dispute or his excitable manner. "I am not too sorry," the 48 year old said. "Please, it was a foul. Of course, I was angry. For me, that is a red card, finished. So my staff were emotional, the staff of Sunderland were emotional but, if you look on your ticket, that is included." "If nothing happens on the pitch, you can watch the bench. But it is over and Mamadou Sakho is okay."
