The former agent of Paris Saint-Germain midfielder Blaise Matuidi is taking the player to court for what he sees as a breach of contract.
Matuidi was contracted to Jean-Pierre Bernes until the end of June but is now represented by Mino Raiola after ending the initial agreement in March.
Bernes says that the approach from Raiola was unlawful and is seeking up to £7.5m from the pair, according to ESPN.
"According to FIFA and French rules, an agent must not contact a player under contract [with another agent]," L'Equipe quotes Bernes's lawyer, Carlos-Alberto Brusa, as saying. "Mr Matuidi was approached by Mr Raiola. That's an established fact.
"While Mr Bernes pays his taxes in France, he is up against an Italian agent whose licence is held in the Netherlands and whose company is based in Monaco.
"The sums Mr Raiola receives in France do not produce a single cent of tax. This absurd situation has to be resolved."
Matuidi has been capped 12 times by France.
