Jurgen Klopp admits Liverpool 'lost their mojo' in Red Star Belgrade defeat

“I don't say it is already serious if we lose twice but we have to make sure it will not happen again otherwise it will be difficult as the next game is already an away game.

“We have to make sure in Paris that we do better.

“There were a lot of moments when we could get in control of the game and we didn't do, we made the wrong decision.

“It just happened. We will talk about it but tonight we can’t change it.”

Klopp claimed the red-hot atmosphere inside Rajko Mitic Stadium did not affect his players but he admitted they made it too easy for the hosts.

The German added: “We made life a bit too easy tonight for Belgrade.

“That is the main problem. They deserved it in the end with the passion they showed. At the end, you have to score goals.

“If you think how often we were in their box, but you have to make the last decision in the right way and we didn’t. That’s why we lost 2-0.

“They wanted to strike back and they did.”
