Manchester United boss Jose Mourinho is furious with the FA after learning that England backroom staff were present at a late-night session with Wayne Rooney on Saturday, Sky Sports understands.

Rooney was pictured in the early hours of Sunday morning with hotel guests who had attended a wedding, with pictures of him emerging in a report in the Sun newspaper on Monday.

The report quoted a source as saying "Wayne was in the bar with members of the FA, drinking beer and red wine", although a spokesman for Rooney has since defended the England skipper's actions.

Sky Sports has been told that backroom staff members who were with Rooney included a coach and members of the medical and support staff, as well as team-mate Phil Jagielka.

The presence of FA employees in the area of the hotel where Rooney was up late and drinking alcohol is understood to have incensed Mourinho.

Sky sources have been told that, while the United boss has no issue with Rooney relaxing on a night off, he is unhappy that the England captain was allowed to behave in this manner while under the responsibility of the Football Association - and that it has since become public.
