Chelsea are reportedly monitoring Bayern Munich centre half Niklas Sule as Thomas Tuchel looks to capitalise on the German's contract uncertainty and bolster his defensive options this summer transfer window.
The 25-year-old has failed to nail down a starting berth in Hans-Dieter-Flick's side in recent seasons, amid speculation that the Bayern boss was left unimpressed by Sule's fitness last pre-season.
The Germany international has made 16 starts in the Bundesliga this season and according to Abendzeitung, Bayern may look to cash in with Sule's contract expiring in 2022.
The Bundesliga champions have been stung by David Alaba's contract stand-off and may look to avoid a similar dilemma with Sule.
