Frustrated players and coaches were not in the mood to deal with supporters - some of whom had jeered them from the stands - when making their way back to the team bus. Amad cut a seriously frustrated figure.
The Mail say that while “the exact nature of the exchange has not come to light”, Red Devils star Amad “was left very upset”. He did not have a smile on his face when fans captured a photo of United players in an elevator, with Alejandro Garnacho delivering the same gesture as Amad - although his actions were slightly more jovial.
