Some more details from what I hear:
In Wallis et Futuna football doesn't exist: no clubs, no leagues, no players. In 2005, because of a dispute, the French FA put an end to the football activity in the islands. Football in Wallis et Futuna was brought in 1926, thanks to the French sailor Alain Gerbault. In the past, several French "stars" used to make some tournées in Wallis et Futuna. The most famous was José Touré, Olympic champion in 1984. Now, the football future is quite uncertain: there are hopes for a football revival in Futuna, but in Wallis, it's in a deadlock.
