The tie is unfortunately being played behind closed doors but the Reds will still be looking to take a positive step towards hopefully going all the way to the final in Gdansk, Poland.
Ole Gunnar Solskjaer put his players through their paces in front of the assembled media and defender Phil Jones was involved following his recent absence.
Kieran O'Hara, who is on loan with Burton Albion, was working with the goalkeepers, along with David De Gea, Sergio Romero and Nathan Bishop.
Notable absentees were Diogo Dalot, Jesse Lingard and Anthony Martial, even though this does not necessarily rule them out of the travelling squad.
