Chelsea are keen to bring Christopher Nkunku to Stamford Bridge in January if they can convince RB Leipzig to let him go early - but are facing a battle with Atletico Madrid to sign Leandro Trossard.
The Blues have agreed a deal in principle to sign the 24-year-old Nkunku. And Leipzig would rather wait until the end of the season to sell him so they have time to find the right replacement.
However, Chelsea are understood to be exploring the possibility of bringing him in sooner than that to boost the numbers at Graham Potter’s disposal. And the hope is that he will arrive before the end of January to give the club further options as they handle their players’ fitness on the back of the World Cup and the busy festive period.
