The players were given Thursday off by Ole Gunnar Solskjaer as they focused on recovery and preparations for Monday’s clash with Arsenal.
There were a number of notable absentees from the get-together.
Paul Pogba, Harry Maguire, Ashley Young, Marcos Rojo, Sergio Romero and Phil Jones gave the trip a miss.
