Warren frequently argued for abolition of the Oceania Football Confederation (OFC), claiming that the OFC offered nothing to either the world game nor to the nations that comprised the confederation. The lack of competition for Australia in the OFC was exemplified by the 2002 FIFA World Cup qualification results that featured 11–0, 22–0 and 31–0 scorelines against OFC opponents. The OFC does not have a direct qualification route to the World Cup. The OFC champion plays in intercontinental playoff series against a team from either CONMEBOL or the AFC for a World Cup berth. Warren favoured a merger between the OFC and Asian Football Confederation (AFC) that would allow the OFC nations to play in a regular qualification series. After the Crawford Report of which he was a committee member, Australia joined the AFC in 2006.
