Liverpool manager Jurgen Klopp appears to be intimidating opposition players with his pre-game actions.

The German head coach has a habit of standing on the halfway line and staring at the opposition before kickoff.

Ex-Premier League goalkeeper Ben Foster and Everton defender James Tarkowski spoke about this ritual.

Asked about the behavior on a Fozcast podcast by Foster, Tarkowski replied: "Always, because I always warm up right near the halfway line. I like to be that end of the warm ups so I'm always quite high and can see him gleaming at me from the side.

"I'm thinking 'I better make sure this pass is right', or he's going to walk into the dressing room and say 'that Tarkowski's having one in the warm-up, go and play on him'."

"That's not the reason," Klopp replied to Foster when asked about the ritual.

"I just want to see, I want to understand. Sometimes you see a player limping a little bit, you see a player doing this or that and I just try to understand what they are doing.

"It's not so interesting when they are doing pure physical stuff, but when they start passing I have a look. Only one time I used it to intimidate an opponent, it's not nice to say that, but it was against my old club when we played Dortmund.

"I knew it would be strange for them so I thought 'come on, let's do it', but besides that if somebody said that I do that on purpose (to intimidate) it's not true. I just watch."
