Manchester United manager Louis van Gaal will fight his Football Association charge for comments he made about the referee after an FA Cup match last month.
Van Gaal made the comments about referee Chris Foy after United were held to a 0-0 draw by fourth-tier side Cambridge United.
"Every aspect of a match is against us," he said at the time.
"Then you have seen the referee. It's always the same. Everywhere I have coached these games and I have coached them also with other clubs, it's always the same."
The Premier League giants won the fourth-round replay 3-0 at Old Trafford on Tuesday.
The 63-year-old says he is surprised at the charge, which the FA says "allege and/or imply bias on the part of the match referee and/or bring the game into disrepute."
"In 30 years as a trainer-coach I have never been charged. I do not think I said something wrong," says van Gaal.
"I said in the press conference before the game that everything is in favour of the underdog."
