The timing of this return is vital as United have several availability issues. Carrick will be without Harry Maguire against Leeds after the England international received a red card against Bournemouth. Furthermore, Matthijs de Ligt remains absent, struggling with a back injury that has kept him out since November.
Additionally, Diogo Dalot and Tom Heaton have remained in Manchester as they recover from illness. Consequently, the return of Martinez provides a necessary reinforcement for the squad as they prepare for the final seven games of the domestic season to ensure they finish strongly.
