Chelsea have been told they need to pay £30 million to sign out-of-favour Bayern Munich defender Mats Hummels, according to the Sun.
The 30-year-old has fallen down the pecking order at the Bundesliga champions and is currently third choice behind Jerome Boateng and Niklas Sule.
The paper says Hummels is unhappy and is keen on leaving the club in the winter transfer window.
Hummels, who has two years remaining on his deal at the Allianz Arena, has made 98 appearance since joining from Borussia Dortmund in 2016.
