Former Liverpool defender Dan Agger admits he's a big fan of manager Jurgen Klopp.

The former HB Koge coach regrets not working with the German while a Reds player.

He told the Athletic: "It has been fantastic to follow (Liverpool under Klopp).

"I'm a little jealous because I wanted to be part of something like that in Liverpool. Klopp is the type of manager I would have loved to play under. What you see is what you get. No bull****. I've always preferred it that way.

"I always worked better when I received criticism rather than positive feedback.

"If I received criticism, my attitude was that now I have to f***ing prove them wrong. What should I use it for if something positive is said?"
