The Ligue de Football Professionnel (LFP) says it "does not understand" the decision by LaLiga to hold up Neymar's proposed transfer to Paris Saint-Germain by rejecting an attempt to pay his release clause, reports football site FourFourTwo.
LaLiga issued a statement on Thursday stating that they had refused to accept a payment of €222million made by a legal team acting on Neymar's behalf that would have released him from his Barcelona contract.
The LFP, the organisation responsible for the major professional leagues in France, has now called on the Spanish body to "abide by the rules of FIFA and its responsibilities" and has offered full support to PSG in their attempts to finalise the transfer.
A statement issued on Thursday read: "The LFP is surprised and does not understand LaLiga's refusal simply to accept the payment of the release clause of the player Neymar.
"The LFP asks LaLiga to abide by the rules of FIFA and its responsibilities.
"The LFP supports Paris Saint-Germain and wishes Neymar to join the Ligue 1 championship.
"The LFP's legal services are in support and at the disposal of Paris Saint-Germain, so that the contract of Neymar can be approved as soon as possible."
LaLiga president Javier Tebas warned this week that they would block PSG's attempts to sign Neymar for the full €222m fee and would take a complaint to UEFA's Financial Fair Play regulators if necessary.
"We will not accept that money from a club like PSG that, without belonging to LaLiga, want to benefit from the rights of our organisation," he told AS.
