Manchester United have reportedly enquired over the availability of Bayern Munich centre-back Niklas Sule.
However, according to Sport1, United have now identified Sule as a potential target, with the 20-time English champions approaching Bayern to enquire about the 23-year-old.
Sule joined Bayern from Hoffenheim in the summer of 2017 and has made 78 appearances for the German champions over the last two campaigns.
An 18-time Germany international, the defender stands at 6ft 5in and would add a serious presence to Ole Gunnar Solskjaer's defence heading into the 2019-2020 campaign.
Sule still has three years left to run on his contract at the Allianz Arena, though, suggesting that United would have to come up with a big offer to tempt Bayern into a sale.
