Manchester United turned Old Trafford's corporate boxes into bedrooms for their players amid anti-Glazers protests outside the stadium.
Supporters set off smoke bombs and flares outside the ground ahead of Sunday's Premier League clash with Liverpool.
The Athletic reports that United anticipated the protests and planned ahead by bringing their players to Old Trafford seven hours early.
To make conditions more comfortable, beds were placed in the corporate boxes if players wanted to rest.
The Red Devils usually stay at the nearby Lowry hotel before home games, which is also used to hold group meetings for players to rest on matchdays.
