A boy and his father playing with a new toy may have caused an international sporting furore between Australian and Honduras, after allegations of "espionage" surfaced when a drone was spotted at Olympic Park.

Honduras coach Jorge Luis Pinto launched a scathing attack on the Socceroos, accusing them of spying on his team, saying it was an embarrassment to Australia.

The Honduran football association, FENAFUTH, accused Football Federation Australia of attempting to film the visitors' training session at ANZ Stadium on Monday evening after a drone was seen flying over the venue. The team's staff filmed the drone as it flew over the players and were quick to suggest it was deployed by the Australians to try and gain an insight into their tactics and preparations.

Speaking at the pre-match press conference for Wednesday night's game, Pinto remained firm with his allegations, suggesting the Socceroos tarnished the reputation of their country.
