Manchester United have been handed a huge injury boost after Amad Diallo trained ahead of their Europa League semi-final first leg with Athletic Bilbao. Matthijs de Ligt also looks set to be passed fit for the game on Thursday night. Amad has been sidelined with an ankle problem suffered in training back in February ahead of the Premier League clash away at Tottenham in what was a significant blow to Man Utd head coach Ruben Amorim. Meanwhile, De Ligt has been absent since picking up a knock during the 1-0 defeat to Nottingham Forest at the beginning. "Amad is near, Matta is near, but the rest is at the same pace," Amorim said of the pair before United’s 1-1 draw against Bournemouth at the weekend. However, both Amad and De Ligt took part in a full training session at Carrington on Wednesday morning as they both look to prove their fitness to the Man United boss ahead of the huge European tie. Toby Collyer was also present as he did some individual training. Meanwhile, back-up goalkeeper Altay Bayindir was back with the group after missing the trip to the Vitality Stadium Joshua Zirkzee, Lisandro Martinez and Diogo Dalot will all miss out against the LaLiga outfit, with the latter a doubt to play again this season after suffering a calf injury. "There is that possibility but I don't know, we will check week by week, because he works really hard, he can recover quite well, so we will see,” Amorim said of Dalot. "He has a problem with his muscle in his calf. He had a sequence of games, he played all the time. “We tried to manage but some of the players have to play a lot of minutes and we have to protect the ones that we think are not so ready to cope with that, but Dalot felt something."
