Nkunku had also attracted interest from other top clubs, including Bayern Munich and his former team RB Leipzig. Chelsea had reportedly rejected a loan move from Bayern, as they sought to sell the player to help their financial situation.
Nkunku's time at Chelsea was marked by struggles to make a significant impact, despite playing 48 matches and scoring 15 goals, with 5 assists. His contributions were mostly in the Conference League.
The transfer details have been confirmed by transfer expert David Ornstein.
Nkunku still had four years left on his Chelsea contract, and several top European clubs were interested in signing him. This shows that he still possesses high quality as a player.
The Paris Saint-Germain academy graduate will now play for AC Milan in the Serie A, where the team is competing for the title.
