The defender would love to see his Germany international team-mate join him in the Bundesliga next season.
Niklas Sule has backed Leroy Sane to thrive at Bayern Munich should the German champions sign the winger from Manchester City.
If Bayern can get the deal over the line then Sule, who has played alongside Sane for the Germany national team, is confident he would be a success in Bavaria.
“Leroy is an exceptional player, Bayern Munich would do well [to sign him]. Not only because of his skills, but he is also a great guy," Sule told Sport1.de.
"I would be very happy if he came, but I do not want to get involved. But I think he knows that Bayern Munich are great.”
Sule also offered his backing to Bayern manager Niko Kovac after an up-and-down first season in charge.
“I would not call myself a fan. He is my coach and I am professional," he added. “We had good moments and started great in the season. Then there was a dip.
“During the winter break, we all looked at each other and said: 'What are we going to do now? We have to change that!'
“We were open with him and then we came out of the difficult situation. We won the double with him despite difficult spells. That speaks for itself.
"Even in a season where there was a lot of writing about us probably not going to get a title. So it goes without saying that I give the coach my backing.”
