Manchester United have approached Bayern Munich about a price for Niklas Sule.

The Germany defender has impressed United scouts and Sport1 says an enquiry has been lodged about Sule's availability.

Sule, 23, has a deal with Bayern to 2021.

And for the moment, Bayern have informed United they're unwilling to do business.

Bayern signed Süle from Hoffenheim for €20m in the summer of 2017.
