Heaven spoke to the club's website about the factors that led him to make the move. Amorim's words of encouragement played a significant role in his decision. Amorim mentioned that United's playing style, which involves a three-at-the-back formation, would suit Heaven's strengths as a left-sided defender. This would allow him to showcase his ability to run with the ball and defend effectively out wide.

Heaven was also drawn to the opportunities available to young players at United. The club gave the most minutes to teenagers in the 2023/24 season, which impressed him. He felt that this was an attractive aspect of joining the team.

Heaven has also spoken highly of the club's fans and the warm welcome he received. He felt the fans were supportive and loving, which made him feel at ease.

Heaven has also credited fellow Londoner Mason Mount with being a big support since his arrival at the club. Mount introduced himself on the first day Heaven was at the training ground and they had a good conversation. Mount remembered a tackle Heaven had made on him in a pre-season match and they have since become friends. Heaven has also mentioned that Bruno Fernandes, the captain, and Patrick Dorgu, who signed around the same time, have helped him settle in.
