During his time at Chelsea, Chukwuemeka played under manager Enzo Maresca, but his appearances were limited to the Carabao Cup and the Conference League. He made only five appearances. Despite interest from RB Leipzig, Chukwuemeka chose to return to Dortmund, a decision that has now been finalized.

Borussia Dortmund has officially announced the signing of Chukwuemeka, who will be with the club until June 30, 2030. The club's statement welcomed Chukwuemeka back, expressing excitement about his return.

Chukwuemeka initially joined Chelsea as a young and talented player, but his time in West London did not quite live up to expectations. He scored one goal in 17 appearances last season, but his performances convinced the club's hierarchy to secure his services on a permanent basis. Dortmund is now aiming to win the title once again, with Chukwuemeka set to contribute to the team's efforts.
