Paris Saint-Germain have warned FC Barcelona they will bring a complaint against FIFA over the Catalans’ pursuit of Adrien Rabiot, according to a report in Diario SPORT. PSG think Barcelona have tapped the midfielder up by speaking directly to the player’s entourage. The complaint has not been launched formally yet, but PSG are said to have sent an official fax to Barcelona.

Barça are said to be “perplexed” at the situation. According to SPORT, when Pep Segura and Éric Abidal traveled to France to negotiate with the player, Barcelona informed PSG of the matter as an act of good faith. The Catalans did this because they wanted to avoid a bad relationship with the Parisian club, but apparently it was not enough.

The report says PSG think Rabiot has already agreed to join Barcelona when his contract expires next year. They are said to think the player’s unwillingness to renew his contract is proof of such a deal. And there is a rumor that PSG’s effort to sign Ivan Rakitić was a sort of attempted revenge for what they consider an illegal approach for their player.
