As the Premier League season approaches, Manchester United is actively reshaping their squad, nearing the signing of Bayern Munich right-back Noussair Mazraoui, contingent on selling Aaron Wan-Bissaka to West Ham. United has already secured Joshua Zirkzee and Leny Yoro and aims to finalize several more transfers, though Jadon Sancho's rumored move to PSG appears unlikely. Chelsea has also been busy in the transfer market, while Liverpool and Manchester City have yet to make significant moves. Arsenal recently signed Riccardo Calafiori from Bologna. United's focus on strengthening their defense is driven by injuries and the need for squad depth, with potential interest in left-back reinforcements due to Luke Shaw's and Tyrell Malacia's fitness concerns.
