Manchester City star Leroy Sane should join Bayern Munich, according to Borussia Dortmund chief Hans-Joachim Watzke.

Dortmund were narrowly beaten by Bayern to the Bundesliga, the latter's seventh title in a row.

However, Watzke does not see the issue if Bayern strengthen by signing Sane from Man City, as rumours suggest.

"I think it would be great if Bayern brings Leroy Sane back as a German national player, because that would further increase the appeal of the league," the Dortmund chief told Bild.

"I am the first to congratulate them [on their title win].

"We want to become champions, but Bayern is like Mount Everest.

"You can try to defeat it once - and we want that too. I think even Germany needs that again soon."
