Bayern Munich supremo Karl-Heinz Rummenigge says Leroy Sane is still underachieving.

The former Manchester City winger is now in his second season with Bayern.

Rummenigge said: “The breakthrough is expected from him, he is not yet the Leroy Sané that he could be according to his talent. He is measured against Robben and Ribéry, that is, by pure world class.

“He just has to take the next step this year, that's just expected of him. The club invested a tremendous amount in him, and the transfer was also difficult to accomplish.

"He can do it, he has to take his fate in his hands and give full throttle."
