The defender has dropped down Erik ten Hags pecking order in recent weeks, having not started a Premier League game since September. The 30-year-old has suffered frequent injury setbacks since joining United in August 2021, sustaining two issues this season already.
Upon returning from his most recent problem, he has been unable to edge out Harry Maguire and Victor Lindelof from the centre-back positions and clubs are now monitoring what happens next.
Sky Germany reports Bayern hold an interest in Varane, although they deem a transfer unrealistic given his wage demands. The report says the German champions have been told a January exit is possible.
Varanes contract runs out in 2025 and United will be required to decide whether to stick or twist in the summer when it comes to a contract renewal, if he is still at Old Trafford by then. If he does leave in January, it is likely to be permanently, and not on loan.
United officials have communicated they are concerned about breaching Financial Fair Play rules so a sale would help ease those worries. Rumours suggest Varane could be sold for between 20m and 30m (17m to 26m).
