Arthur Vermeeren, a 20-year-old Belgian defensive midfielder, is on loan at Marseille from RB Leipzig for the current season. Marseille has an option to make the move permanent, but that would not prevent a summer move from Manchester United. Vermeeren's contract with his parent club, RB Leipzig, is valid until June 2029, and he has made 11 appearances in the current Ligue 1 season.
