Nigeria vs Bosnia and Herzegovina World Cup 2014: 20,000 sign petition after referee Peter O'Leary is spotted 'celebrating' win

Edin Dzeko brands ref 'shameful' after having a goal wrongly ruled out

An online petition has already drawn 20,000 signatures to remove referee Peter O'Leary from the World Cup after an image appeared of him 'celebrating' with Nigeria goalkeeper Vincent Enyeama.

The New Zealand referee drew widespread criticism after wrongly disallowing an Edin Dzeko strike after 21 minutes.

Eight minutes later Peter Odemwingie fired the Super Eagles in front, but Emmanuel Emenike appeared to clip the heels of Emir Spahic in the build-up.

That went unpunished and the appearance of the picture has prompted a Bosnian fan to send a petition to Fifa asking for the removal of O'Leary and the match to be changed to 1-1.
