Liverpool boss Jurgen Klopp was effusive in his praise of Atletico Madrid manager Diego Simeone ahead of their Champions League last-16 tie on Tuesday.

The reigning champions head to Madrid to face the notoriously disciplined Atleti, lead by their emotional boss Simeone.

Klopp has also been known to show passion on the sidelines, but he believes he is nowhere near the level of the former Argentina international.

"People say about me that I'm emotional on the sideline. If I'm on level four, I would say Diego is on level 12 or so," he told reporters.

"It's really like I'm the Kindergarten Cop against him.

"That's over all those years, eight years, that's really long and still having this emotional level, wow, that's absolutely impressive.

"His teams are always world-class organised, so that makes him one of the best. We met once or twice, exchanged some messages after big defeats or big wins and tomorrow in a really competitive game we meet for the first time, it will be interesting."

Asked if he can highlight any differences in playing style between him and Simeone, Klopp replied: "I don't know him well enough to know where the differences in style or managing or stuff like that. He was a world-class player, I was not a world class player, we can say that easily."
