Wigan manager Roberto Martinez is considering whether to appeal against his £10,000 ($15,700) fine for criticising a referee.
Martinez was this week found guilty of misconduct by the
The Spaniard, who was angered by a number of decisions in the Premier League game, accepts his remarks could have been interpreted that way but feels he was misconstrued.
Martinez said: "We have had the hearing and now we are waiting [to see] if we can appeal the decision because it is something I don't agree with.
"At the moment it is one of those situations you have to accept but we will look into the written outcome and see if we can appeal it.
"If you see the comments they are not disrespectful comments at all to the referee.
"I wasn't talking about the referee, I was talking about the figure of the referee in those certain games.
"I was talking about the experience that we at Wigan Athletic have had going away from home and unfortunately the calls we have had of late.
"I would never question the integrity of the referee or question if the referee was biased towards a decision."
Martinez said in the aftermath of the game that it felt as though his side was "fighting against a mountain".
He said at the time: "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.
"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."
Wigan expects to receive the written judgment from the FA before the weekend and must make a decision regarding an appeal by Monday.
