Bayer Leverkusen legend Jens Nowotny says Kai Havertz would flourish under Jurgen Klopp at Liverpool.

Liverpool and Manchester United are both tracking the 20-year-old.

And Nowotny believes Havertz should choose to join the Reds because of Klopp's presence.

"He is on the way to becoming a world-class player. He has huge potential," Nowotny told Goal and Spox.

"Another year in Leverkusen would certainly not hurt him.

"For his personal development as a player and as a person it would be good for him to be in an environment in which he feels comfortable - and that's the case in Leverkusen. Otherwise he would not have already spent 10 years at the club.

"To fulfil his potential, the next step is very, very important. He has to ask himself questions: are there clubs where he can develop if there is a possible change? Or are there only clubs where he has to arrive and function as a finished player?

"On the one hand, you need coaches like Jurgen Klopp, Pep Guardiola or Jose Mourinho, who can take him further. On the other hand, such a coach also has to work for a club where he is allowed to develop."
