Liverpool defender Ozan Kabak is being backed to prove himself at Anfield.

Liverpool have the option to sign Kabak on a permanent basis in the summer for £18million if he impresses during his loan spell from German club Schalke.

"Kabak is a good player," said Guido Schafer, a former team-mate of Klopp's at Mainz and a journalist currently covering RB Leipzig.

Schafer also told the Under the Radar podcast: "I saw him a lot times in the Bundesliga.

"He is very powerful and he has a good mentality. I think £18m is a good price for this player.

"The mentality is world-class from Kabak. He is not in his best performance now but I think he could be a good player for Klopp and Liverpool for the future."
