Wigan manager Roberto Martinez has been fined £10,000 after admitting a charge of misconduct in relation to comments made after his side's game against Manchester United last month, the Football Association have confirmed.
A statement on the FA website read: "The charge was in relation to a 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. Martinez, who had requested a personal hearing, was also warned as to his future conduct."
The Spaniard was frustrated after his side's 4-0 defeat at Old Trafford, during which England striker Danny Welbeck was awarded a controversial penalty following what seemed to be minimal contact from Ali Al Habsi.
