Chelsea boss Thomas Tuchel is keen on landing the signature of RB Leipzig defender Dayot Upamecano in the summer.
The Frenchman has a £38m release clause on his contract which becomes active in June and he has been tipped to pursue a new challenge.
Bayern Munich are deemed as favourites to land his signature with the hierarchy already in contact with Leipzig and his agents.
However, according to Kicker, Tuchel is eager to bring the centre-back to Stamford Bridge and has urged the Blues’ board to make a move.
Fikayo Tomori is presently on a short-term loan at AC Milan, but the Rossoneri have the option to buy him for £25m at the end of the campaign.
There are suggestions that Christensen could head for the exit door this summer to pave the way for the arrival of another centre-back.
