Liverpool are rumoured to be interested in Borussia Moenchengladbach's tireless midfielder Mahmoud Dahoud.
The 20-year-old midfielder impressed in the Bundesliga last season, playing 32 times, scoring five goals and making nine assists.
The youngster has played on two occasions for Germany's Under-21 side and Klopp is said to be a keen admirer.
However, Moenchengladbach do not intend to sell the player.
"Dahoud is not for sale. We are a hungry club and we need every good player," said the club's sporting director, Max Eberl.
