Roberto Martinez has been charged by the FA for comments made about the referee following Wigan's defeat at Manchester United on September 15.
The Latics lost 4-0 at Old Trafford during which he was unhappy about a penalty awarded to the hosts as well as a Danny Welbeck challenge on Franco di Santo which he felt warranted a red card.
After the match, Martinez said: "I have come to United three times before today and for whatever reason we don't seem to be measured in the same manner as the team at home.
"Today the penalty is as bad a decision as you are going to see in the Premier League.
"In many ways, you feel as though you are fighting against a mountain.
"There were tackles flying around that if they had been the other way round there would have been a couple of red cards."
