Manchester United duo Mason Mount and Lisandro Martinez were absent from midweek training | OneFootball

Manchester United duo Mason Mount and Lisandro Martinez were not involved in first-team training during the week, according to journalist Samuel Luckhurst.

Mount last played for Man United in January and has missed the last six games, with Red Devils manager Michael Carrick revealing back on February 1 that the Englishman would return very soon after suffering a knock in training.

The nature of Mount’s injury is unknown but he has yet to return to training while Martinez has been out for three weeks and is set to miss a fourth consecutive fixture following a minor setback after a calf injury.

Carrick promoted 18-year-old centre-back Albert Mills to first-team training on Wednesday but he is unlikely to be named in the matchday squad against Aston Villa on Sunday.

Man United under-21s play their Southampton counterparts in the Premier League 2 tonight and Mills is expected to feature.

The Norwich-born youngster once trained with the Red Devils first-team under Ruben Amorim last October and would have been delighted to be back during the week.

Mills has been a regular for the youth teams this term, with 17 starts to his name in the under-18 Premier League and three appearances for the under-21s.

He bagged a goal as the under-18s secured a comfortable 4-1 win over Oxford United in the FA Youth Cup last month and will hope to feature more in subsequent first-team trainings.

Matthijs de Ligt was also unavailable in training this week as he continues to nurse a back problem, while Patrick Dorgu is yet to fully recover from his hamstring injury.

Man United will be desperate to return to winning ways following the 2-1 loss to Newcastle United last time out.

They face Bournemouth next after the Villa game and will look to head into the international break with back-to-back league victories.
