Jonny Evans believes Manchester United have been getting a raw deal off referees this season.
The Northern Ireland international feels the reigning Premier League champions have not been getting the benefit of some 50-50 decisions in recent games.
United boss Sir Alex Ferguson and a number of players were unhappy with a host of decisions given by referee Martin Atkinson during last weekend's defeat at Chelsea.
United were aggrieved Atkinson awarded a foul against Darren Fletcher for a challenge on Ashley Cole in the build-up to Chelsea's winning goal, while they felt Didier Drogba pulled Wes Brown's shirt as John Terry scored the winner.
Evans believes United are having to beat the officials on some occasions to get results.
"We are usually quite good with referees," Evans told Sky Sports News. "I think there are a lot of teams that do a lot of playacting, but I don't think that's the case with Manchester United.
"I think we do try and play fair and not many of us would roll around and try and cheat.
"Sometimes the 50-50 decisions, that you would hope because of that would go in your way, have not been really going our way lately and I think that's what has maybe been disheartening a few of the lads, but that's football.
"Sometimes you have got to beat the referee as well and that is what we are going to try and do."
