The Reds were put through their paces by Ole Gunnar Solskjaer and his coaching staff before the anticipated first leg of our Champions League quarter-final against the Spanish champions and La Liga leaders.
Solskjaer oversaw the session at Carrington, where the cameras filmed the first 15 minutes as per UEFA rules.
Former Barcelona player Alexis Sanchez and fellow forward Marcus Rashford were both involved, which is encouraging news following their recent troubles with injury.
Rashford, who missed our last outing at Wolves, went through a separate stretching warm-up before joining in with the rest of the squad.
