Arsenal manager Arsene Wenger says rumours about Manchester United boss Louis van Gaal's position are "disrespectful".
Dutchman Van Gaal's future at Old Trafford is reported to be in doubt after a run of six games without a win.
Jose Mourinho, who was sacked as Chelsea manager last week, has been linked with the Old Trafford job.
"I do not want anyone to lose their job. My personal feelings on that front is that it is always sad," said Wenger.
Later on Wednesday, Van Gaal walked out of his own pre-Boxing Day news conference - which lasted four minutes 58 seconds - after answering just three questions from reporters.
