Under-pressure Manchester United manager Louis van Gaal answered just three questions before walking out of a news conference on Wednesday.
The 64-year-old Dutchman was unhappy at being asked about his future following speculation that he could be sacked.
The media briefing, ahead of Saturday's game at Stoke, lasted only five minutes before Van Gaal's departure.
The former Netherlands boss said he had only turned up to speak to journalists because of Premier League rules.
As he left, he told the reporters: "I wish you a merry Christmas and maybe also a happy new year when I see you. Enjoy the wine and a mince pie. Goodbye."
United are without a win in six games, having lost their last three matches to Wolfsburg, Bournemouth and Norwich.
