West Ham United boss Sam Allardyce has called on the FA to appoint more officials in order to cut down the amount of refereeing mistakes.
"This is a difficult period for referees," Allardyce explained.
"Why do they always seem to make more wrong decisions now?
"It's probably because they are overworked and they are fatigued and the system has to be looked at. Referees are travelling all over the country and out in Europe and have been since the start of the season.
"There's not enough of them. They try their very best to get things consistently right, but it happens every year around this time of year. They need to ease the load on the referees we have. The game needs to move on and look at recruiting better refs from all avenues."
