Chelsea needs to sell some players before they can complete the Simons deal, and Nkunku's transfer could be one of the players who leaves the club. Leipzig is aggressively pursuing Nkunku, who is interested in returning to the Bundesliga.
Leipzig's move for Nkunku will likely give Chelsea the freedom to complete their deal for Simons. Bayern Munich has also shown interest in Nkunku, but their earlier loan bid was rejected by Chelsea.
