Lisandro has been recovering from an ACL injury sustained in February and has been gradually working his way back to full fitness.

According to the club's plans, Martinez is expected to make a playing return after the international break in November.

United will aim to reintroduce him to the first team gradually, starting with individual training sessions at Carrington.

Manager Ruben Amorim has been including Martinez in team meetings and discussions, indicating that he is confident in the Argentine's ability to make a successful comeback once he is fully fit.
