Two of Manchester United's academy stars could be set for Champions League bows after training with the first team on Tuesday.
With qualification for the Champions League knockout stages already secured ahead of Wednesday's trip to Valencia, Jose Mourinho will not take any risks and is likely to rest a number of players.
Teenage duo Mason Greenwood and James Garner both took part at Carrington and could feature at Mestalla while Anthony Martial, Luke Shaw and Chris Smalling were all absent.
There was more positive news, however, with Eric Bailly returning to the group.
Bailly played his first match for two months in last week's draw with Arsenal but then sat out Saturday's victory over Fulham, which Martial and Shaw also missed.
Smalling started that game but was replaced in the second half after suffering an injury.
Mourinho has already announced that Paul Pogba, who has been left out of the starting line-up for the last two games, and Andreas Pereira will start, and goalkeeper Sergio Romero is also set to play.
Diogo Dalot, who has shone on his first two Premier League starts, looks likely to be rested after missing training along with fellow defender Matteo Darmian, while Victor Lindelof and Alexis Sanchez are definitely sidelined through injury.
