Roberto Martinez says Mike Riley apologised for refereeing mistakes

Wigan Athletic manager Roberto Martinez says he has received an apology by referees' chief Mike Riley for mistakes made by officials during Saturday's 2-1 defeat at Chelsea.

Both of the home side's goals at Stamford Bridge appeared to be offside - something that Martinez said was "disgusting" after the game.

But speaking before Wednesday's match against league leaders Manchester United, he says Riley's actions in contacting the club were "very honourable".
