Manchester United manager Louis van Gaal says an FA Cup defeat at Derby on Friday could get him sacked - for the fourth time this season.

Speaking before Friday's fourth-round match with the side fifth in the Championship, Van Gaal said questions about his future were being asked in a "disrespectful way".

Manchester United: Are they stuck in the past?

"You make your stories and people believe it," he said at a news conference. "I am concerned they are believing it.

"It is the third time I am sacked and I am still sitting here."
Van Gaal praised the "fantastic" support of executive vice-chairman Ed Woodward but said it brought "more pressure" to "fulfil the expectations that they have of you".
The former Ajax, Barcelona and Bayern Munich boss also reiterated his desire to "continue to the end" of his three-year contract, which runs until the finish of the 2016-17 season.

What does Lawro think?

"A lot will depend on the team that United boss Louis van Gaal puts out but I just do not see United going there and rolling the Rams over. Derby are a good side by Championship standards. They will be very competitive, they will play at a high-tempo and they will cause United some problems. 1-1."

Can the FA Cup save Van Gaal?

Famously, former United boss Sir Alex Ferguson was under pressure three years into the job at Old Trafford when his team faced Nottingham Forest in the FA Cup third round in January 1990.
It was thought defeat would cost Ferguson his job, but United won 1-0 and he went on to become English football's most successful manager.
Asked whether the FA Cup could become his saviour, former Barcelona, Bayern Munich and Ajax boss Van Gaal said: "Of course."
