Neymar's lawyers may have found a way to force through a Paris Saint-Germain exit next summer, according to a report.
The Brazilian has been desperate to leave the Parc des Princes and return to former club Barcelona, with Real Madrid having also shown an interest.
According to Mundo Deportivo, the 27-year-old could invoke Article 17 of the Fifa regulations on the Statute and Transfer of Players.
The clause enables a player to terminate their contract after three years' service if they are under 28-years-old.
PSG would be due compensation if Article 17 was to be triggered, which Neymar's lawyers have predicted to be around £154m.
The player will have 15 days after the last official match of the season to formally notify the Ligue 1 champions of his intention to trigger Article 17.
The loophole has been used before, when Heart of Midlothian defender Andy Webster forced through a move to Wigan in 2008.
