Rooney ready to face Arsenal
The eyes of the world will descend upon the Theatre of Dreams this weekend, with old adversaries Jose Mourinho and Arsene Wenger set to rekindle their managerial rivalry.
With plenty riding on the contest, both sides could be forgiven for feeling the tension as the build-up intensifies.
United, though, looked to be in relaxed mood as it was put through its paces on Friday.
The wintry conditions at Carrington forced the Red Devils to wrap up warm, but there was some fun to be had – with Jesse Lingard and Paul Pogba making the most of the opportunity to have a snowball fight.
Bastian Schweinsteiger continues to work with the first-team squad, despite being frozen out of the picture by Mourinho.
Henrikh Mkhitaryan was also involved on Friday, as he looks to force his way into the fold after a high-profile summer switch.
Zlatan Ibrahimovic could also be seen under the mass of beanies and snoods, but he will play no part against the Gunners this weekend as he serves a suspension.
Mourinho will hope that he is absence is not felt on the day, and that the feel-good factor from the training field can be carried over into competitive action.
