Bayern Munich have given Chelsea an opportunity to sign defender Mats Hummels in the January transfer window.
The German club value the centre-back at £30 million, and they could be prepared to let the defender go, on one basis.
As per the Metro, Chelsea will have until January 14th to decide whether they want to acquire Hummels to bolster their defensive ranks.
The report states that boss Maurizio Sarri is looking for an experienced head at the back, and the 30-year-old could fit the bill.
Bayern are also interested in signing Blues youngster Callum Hudson-Odoi and have already made two bids for the 19-year-old.
