According to reporter Philipp Hinze, Red Bull Group CEO Mintzlaf personally intervened in the deal to join Chelsea, and he negotiated with Chelsea.

In the current situation, Chelsea can only provide a formal offer for Simmons if the player is sold first. Therefore, it is possible for the two clubs to swap players, such as adding Nkunku to the deal. Leipzig's asking price for Simmons is still 70 million euros, and only a few days before the transfer window is closed, and Chelsea still needs to sell players to facilitate the deal.
