Roberto Martínez has been charged by the FA after criticising the referee following Wigan's defeat to Manchester United on 15 September.

Martínez, unhappy with a first-minute penalty decision made against his side by Michael Oliver, suggested referees were more likely to award key decisions to bigger clubs.

"Sometimes it is true," he told reporters. "You look at the incident and you analyse the games you had and just by the law of averages you should get wrong decisions going your way and sometimes it is difficult to understand we don't get that.

"It is difficult in certain aspects, certain games that you never get wrong calls going your way."

An FA statement said: "The charge is in relation to an alleged breach of FA Rule E3 concerning media comments which implied that the match referee and/or match officials in general are motivated by bias and/or brought the game into disrepute."

Martínez has until 4pm on Thursday 27 September to respond to the charge.
