Manchester United make move for Bayern Munich star – report
The Red Devils have conceded 48 goals this season and Ole Gunnar Solskjaer is keen to bolster his defensive options ahead of next term.
Sule has emerged as a leading target for United, who have reportedly sounded Bayern out over a potential £51.9m transfer.
The former Hoffenheim man has become an integral part of Niko Kovac’s team this campaign, making 27 appearances in the Bundesliga.
Bayern see the 23-year-old as the future of their defence, although they could be willing to listen to offers in excess of £50m.
Sule is contracted at the Allianz Arena until 2022, but United hope to bring him to Old Trafford ahead of next season.
