Liverpool boss Jurgen Klopp has put the club's young players on notice.

He says his speciality is developing young players, citing the example of Robert Lewandowski whom he signed from Lech Poznan at the age of 21 and turned into one of Europe's leading strikers at Borussia Dortmund.

"When I manage a club, each young player should smile because the chance is bigger for them than it ever was," said Klopp. "The door is pretty wide open and I don't care about experience. Experience is an important point, but not the most important.

"Of course if a player is on a top level already and you can hold this for two or three years, then everything is perfect. But the young guns are very interesting. That's what I enjoy doing.

"The will to improve is the most important thing for a Jurgen Klopp player. Character. The biggest satisfaction you can get is when you take a player from Poland, from a small club and watch him playing today.

"The difference between that player and the player he is today is unbelievable. I'm not self-confident enough to think I have had the only role in his [Lewandowski's] development, but of course I did play a big part. We all know the best players of today. Tomorrow we don't know, so we can work for this."
