Decisions on which players Manchester United should transfer can vary based on the team's current needs, performance, and the transfer market. As of my last knowledge update in January 2022, I don't have access to specific, up-to-date information on the current state of the team or potential transfer targets.The transfer decisions are typically made by the club's management, coach, and scouting team. They consider factors like a player's performance, fitness, contract situation, and how they fit into the team's tactical plans. For the latest insights on potential transfers, it's best to follow Manchester United's official announcements and the latest news from reputable sports sources.
