Manchester United boss Louis van Gaal says he regards the FA Cup highly.
Having already faced lower division opposition away in the last two rounds, the United boss knows what to expect from League One Preston on Monday.
"The FA Cup is fantastic," said Van Gaal. "You know the world is against you because everybody is for the underdog.
"The chance you can survive is higher because you are playing against lower quality but you have to beat a team with big motivation."
