Keith Hackett has admitted he is worried about Jurgen Klopp’s touchline behaviour at Liverpool.

Speaking exclusively to Football Insider, the ex-FIFA and Premier League referee claimed the FA may give the German a warning after his antics in the technical area against West Brom.

Klopp was left fuming at the end of the first half after Conor Gallagher stayed down when he was fouled by Sadio Mane.

The Daily Star report he felt it was Mane that had been fouled and shouted: “How can he [Mike Dean] do that?”

Asked for his assessment of Klopp’s outburst, Hackett told Football Insider correspondent Connor Whitley: “He’s not questioned the integrity of the referee, he’s passed an opinion.

“Ultimately at the end of the day, Klopp benefited from Dean!

“I do worry about him in the technical area. I do think he’s very animated and it’s not for the first time that I’ve received a lot of comments about his attitude in the technical area.

“Sometimes when the game is over he comes to the referee to have a go.

“I would recommend, there was an opportunity for the referee to put it in his report and maybe the Football Association viewing what they’ve seen and hearing what’s happened can always, as they’ve done in the past, send a letter to Jurgen Klopp suggesting that he might want to refrain from making comments in the technical area.”

Klopp and Liverpool benefit when Dean incorrectly gave them a free-kick when he came together with Fabinho that led to their equalising goal.

They were also handed a lifeline when West Brom thought they had scored a second only for it to be ruled out for offside.
