Wigan manager Roberto Martinez has indicated he could appeal against a £10,000 Football Association fine he received for suggesting a referee was biased.
The FA found Martinez guilty of misconduct after he criticised Michael Oliver for his performance during Wigan's 4-0 defeat at Manchester United last month.
United striker Danny Welbeck was awarded a penalty early in the game, which Martinez claimed was "as bad a decision as you are going to see in the Premier League".
He also argued that he felt as if his side were "fighting against a mountain", and that his team were not treated fairly by referees on their visits to Old Trafford.
Martinez asserts that his comments were about refereeing in general rather than Oliver in particular, and his considering whether to appeal.
Wigan expect to receive a written judgement from the FA regarding the fine on Friday and must make a decision on whether to appeal by Monday.
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 has made four visits to Manchester United as Wigan manager, suffering four defeats while seeing his side concede two penalties and pick up three red cards.
He said after last month's defeat at Old Trafford: "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."
