Salmon, who is 16 years old, has the ability to play as a center-back or full-back, which made him a viable option for the team. Arteta was pleased with Salmon's performance and the experience he gained from playing in the Champions League.

Salmon's debut in the Champions League makes him the sixth-youngest player to participate in the competition's proper matches. He joins a group of talented young players who have achieved this milestone, including Max Dowman, Youssoufa Moukoko, Lamine Yamal, Céléstine Babayaro, and Rayan Cherki.
