Chelsea have offered several players to RB Leipzig for midfielder Xavi Simons, including Christopher Nkunku.
It's part of the complex negotiations with the Blues keen to offload players having also offered both Carney Chukwuemeka and Tyrique George.
Any deal between the two clubs would not be a direct swap deal and would be related but separate transfers. It remains to be seen whether the German club deem it viable.
However, the nature of the negotiations highlight Chelsea's intention to offload attackers to sign attackers in the last few weeks of the transfer window.
Sources close to Nkunku have also explained he is reluctant to join a club like Leipzig as he is aiming to play at Champions League level next season.
