Manchester United are expected to prioritise defensive signings when they head into the January transfer window.
Erik ten Hag's side have been plagued by injury across the pitch, but their performances at the back have been an increasingly worrying cause for concern.
United recently leaked three goals to Manchester City and Newcastle, and conceded four in the Champions League against Copenhagen.
Much of their more defensive-minded players have been among the injury list, such as midfielder Casemiro and Argentina centre back Lisandro Martinez, so ten Hag will undoubtedly prioritise buying a defender.
