Four Manchester United first teamers who have been on the club’s 14-man casualty list have returned to training, pictures showed today.

Long-term absentees Marcos Rojo and Antonio Valencia were in the 20-man squad that took part in full training at the club’s Carrington headquarters on Wednesday morning.

Valencia has not played since October after undergoing foot surgery while Rojo has been out since November with a dislocated shoulder.

Jesse Lingard, who suffered a minor injury in Monday’s 3-0 FA Cup win over Shrewsbury Town, took part in training, as did Adnan Januzaj, who has been out with a hamstring problem.

But David de Gea did not take part in the session, which suggests he will not return in time for Thursday night’s Europa League second leg clash against Midtjylland.

Another notables absentees included Chris Smalling and youthful pair Cameron Borthwick-Jackson and Will Keane, who both sustained injuries against Shrewsbury.

Injury boost: De Gea is closing in on United return

Green giant: De Gea is closing in on return but did not train on Thursday

De Gea was one of 14 players unavailable for selection for the first leg in Denmark last week after injuring his knee in the warm-up.

United must overturn a 2-1 deficit after losing the first leg of the last-32 match against the Danish minnows.

In other Manchester United injury news, Matteo Darmian is closing in on a return after dislocating his shoulder but he was not in the 20-man squad that trained on Thursday.

Goalkeepers: Sergio Romero, Joel Castro Pereira. Defenders: Donald Love, Joe Riley, Marcos Rojo, Guillermo Varela, Daley Blind, Regan Poole, Paddy McNair. Midfielders: Morgan Schneiderlin, Ander Herrera, Michael Carrick, Antonio Valencia, Jesse Lingard, Adnan Januzaj, Andreas Pereira, Juan Mata. Forwards: Marcus Rashford, Memphis Depay, Anthony Martial.
