United have also shown interest in the 26-year-old defender, but West Ham currently lead the race for his signature. If the Red Devils want to go ahead with an offer for Mazraoui, they would first need to offload Aaron Wan-Bissaka, as reported by The Athletic. The 26-year-old right-back has already declined a move to West Ham, preferring a transfer to Inter Milan, either this summer or as a free agent when his contract expires in June 2025.
