Barca could invoke transfer clause to re-sign Neymar

Spanish giants determined to land Brazilian this summer
Barcelona are ready to invoke a little-known clause in FIFA's transfer regulations in order to seal a move for Neymar this summer, according to ESPN.
Article 17 of FIFA's transfer regulations was drawn up in 2001 in response to a dispute with the European Commission over the freedom of movement of footballers in the EU compared to other workers. It states that states that players can leave their contracts "without just cause" once a three-year protection period ends.
Neymar will have been at Paris Saint-Germain three years this summer, so Barca are ready to test the system and see whether they can pull off a sensational deal to bring the Brazilian back to Camp Nou.
