According to the BBC, Chelsea has provided Leipzig with several players in exchange for Xavi Simmons, including Nkunku.
reported that Chelsea's player exchange with Leipzig is part of the complex negotiations, and Chelsea hopes to let several players go, and they also provide Chuk Umeka and George.
No deal between Chelsea and Leipzig will be a direct swap, but a related but independent transfer. Whether Leipzig believes the deal is feasible remains to be seen.
However, the nature of the negotiations highlights Chelsea's intention to sell the attacker in the final weeks of the transfer window to sign a new attacker.
Sources close to Nkunku said he is unwilling to join a club like Leipzig because he hopes to compete in the Champions League next season. Chelsea also appreciated Nkunku's outstanding performance in the Club World Cup, but he is believed to be looking for a team that can play a more important role.
Another goal of Chelsea is Garnacho - currently in the preliminary contract negotiation stage.
Jackson, who has rumors with Newcastle, may be allowed to leave the team to make room if he receives a suitable offer. If the right player transfer is not reached, Chelsea may re-incorporate Jackson and others into the team's lineup.
