Chelsea have been urged to offer for Bayern Munich defender Mats Hummels.
The Sun says Bayern have advised Chelsea to hack up £30million by January 14 on the off chance that they need Hummels.
The Germany center back is never again a programmed pick with the Bundesliga giant and Chelsea need him to enhance their back line.
Hummels, 30, is keen on a move and Stamford Bridge big bosses approached Bayern at a cost.
The Germans have set a due date so they have sufficient time to get a substitution before the transfer window stop.
Hummels won the World Cup with Germany in 2014 and has for quite some time been regarded as one of Europe’s best defenders.
