Jurgen Klopp says he and Chelsea striker Diego Costa 'could never be friends'

Liverpool manager Jurgen Klopp admits he and Diego Costa could "never be friends" after another controversial game by the Chelsea striker.

The Spain international won a penalty, subsequently saved by Simon Mignolet, slightly theatrically and generally antagonised those at Anfield throughout Tuesday's 1-1 draw in the Premier League, with the type of performance which has seen him criticised in the past for going to ground easily.

If I had played against Costa, I could never be friends, that's how it is, but when you have him in your team, it's much more fun.

However, Costa also caused Liverpool enough problems for Klopp to acknowledge his qualities.

"If I had played against Costa, I could never be friends, that's how it is, but when you have him in your team, it's much more fun. He is a warrior," said Klopp.

"What [Antonio] Conte is doing with Chelsea is outstanding but Chelsea without Costa this season?

"He is not the nicest guy on the pitch but I saw no real big incident and until someone tells me something...

"If someone tells me it was a dive, maybe I will be angry tomorrow but that would be the wrong decision what, number 27, but it doesn't make it better."

Klopp was furious with the award of a penalty after Costa tangled with Joel Matip and took out his frustration on the fourth official.

However, after Mignolet came to Liverpool's rescue, the Reds boss calmed down sufficiently to make an apology to Neil Swarbrick in the technical area.

"It was a foul before in my opinion on [Dejan] Lovren, that's what I was a little angry about," Klopp said.

"No one can beat us, was what I said [to Swarbrick]. Obviously that's not true but it felt for us like this in that moment.

"I was absolutely the wrong person to say it. I said sorry - I was a bit excited. He said, 'no problem. I like your passion'."

That passion was reflected around Anfield as the crowd responded to a performance Klopp had promised them after three successive home defeats, which included two cup exits.

"I am happy about the performance. I thought we did well. From the first second we were in the game, we were aggressive," he said.

"The red shirts had passion, readiness, greed, against experience and coolness and that's difficult."

Klopp refused to criticise Mignolet for Chelsea's goal, scored from a quickly-taken free-kick by David Luiz while Liverpool's goalkeeper was looking the other way, which was cancelled out in the second half by Georginio Wijnaldum.

"It was really smart, really clever and really well done - we have to respect that," he said.
