The Fédération Internationale des Associations de Footballeurs Professionnels (English: International Federation of Professional Footballers), generally referred to as FIFPRO, is the worldwide representative organisation for 65,000 professional footballers. FIFPRO, with its global headquarters in Hoofddorp, Netherlands, is made up of 66 national players' associations. In addition, there are four candidate members. Lionel Messi have the most appearances in the FIFPRO World 11 with 16 appearances, whereas Cristiano Ronaldo has had 15 appearances occupying the second place. History On 15 December 1965, representatives of the French, Scottish, English, Italian and Dutch players' associations met in Paris, with the objective of setting up an international federation for footballers.

The emphasis was thereby laid on the freedom of the football player to be able to choose the club of his choice at the end of his contract. FIFPRO supported Belgian footballer Jean-Marc Bosman in his judicial challenge of the football transfer rules which led to the Bosman ruling in 1995. In 2013, FIFPRO launched a legal challenge against the transfer system. Phillipe Piat, the FIFPRO president at the time, said "the transfer system fails 99% of players around the world, it fails football as an industry and it fails the world's most beloved game".
