While it is increasingly appearing that Barcelona star Neymar Jr's transfer to French giants Paris Saint-Germain could become a reality, the Spanish league governing body President, Javier Tebas has questioned the legality of the transfer and threatened to take the matter as far as the Court of Arbitration for Sport (CAS) and the European Union for adjudication.
According to Spanish newspaper AS, Tebas responded to PSG president Nasser Al-Khelaifi who hinted the signing could be close in an interview on Tuesday, and alleged that the French side could break the Financial Fairplay (FFP) laws with the transfer.
"If PSG come with the money for Neymar's [release] clause we will not accept it," he said. "They are financial dopers, breaking FFP laws.
"We will not accept money from a club who, without belonging to LaLiga, wants to take advantage of a right of our organisation – even more when this club is breaking rules and laws.
"If UEFA do not react, we will present an FFP complaint immediately. The complaint is ready and will be presented to UEFA, to the European Union and the Swiss courts (CAS), which are the courts that have jurisdiction.
"Basically, what will be denounced is the unfair competition that involves competing against teams that receive economic injections from countries.
"PSG are a clear example of financial doping. Their accounts show more commercial income than Ream Madrid or Manchester United. Well, that's impossible.
"The truth is UEFA have not been able to control the situation, so action must be taken within the EU's competition sphere."
Neymar is the subject of a €222million transfer from PSG and was excused from training by Barcelona coach Ernesto Valverde even as the speculations rage on.
