Manchester United manager Louis van Gaal has been charged by the Football Association for comments he made after the Reds' FA Cup fourth round stalemate at Cambridge United last month.

"It is alleged that the Manchester United manager’s comments allege and/or imply bias on the part of the match referee and/or bring the game into disrepute," read a statement on the FA's website.

"He has until 6pm on Monday 9 February 2015 to respond to the charge."

After the goal-less draw, the Dutchman told the media: “Every aspect of a match is against us. We have to come here, the pitch isn’t so good, that can influence that you can play in another style.

"Then you have seen the referee – it’s always the same. Everywhere I have coached these games, and I have coached them with other clubs, it’s always the same."
