Barcelona defender Gerard Pique has been accused of making millions of pounds from the Spanish Super Cup's controversial move to Saudi Arabia.
Pique is alleged to have helped broker a deal with Spanish FA (RFEF) president Luis Rubiales to take the competition to the Middle East.
Spanish newspaper El Confidencial allege that the RFEF included two clauses in its contract with the Saudi authorities to ensure Pique's company Kosmos will take €4m (£3.3m) for each tournament held in the country over a six-year period, totalling €24m (£19.9m).
According to the report, the RFEF will earn €40m (£33.1m) for each edition of the Super Cup held in the country.
El Confidencial claim to have access to voice recordings and documents relating to the agreement and have alleged that Rubiales attempted to hide Pique's participation in the deal.
In one of the recordings, Pique allegedly responds to Rubiales' suggestion that Real Madrid wouldn't agree to play outside of Spain less than €8m (£6.6m).
"If it's about money and [Real Madrid] would go for €8m euros, then they get paid €8m euros and Barcelona get paid €8m too, then the others get paid €2m and €1m," Pique is alleged to have said.
"That's €19m and you, the federation, keep €6m.
"We could even push Saudi Arabia for more, saying that if not then Real Madrid might not come.
"Rather than you hosting in it Spain where you won't even make €3m, think about this."
Pique's alleged involvement in the deal could be deemed as a conflict of interest, given he remains a player for Barcelona.
It is claimed that Pique didn't charge a commission directly to the RFEF in order to avoid breaching any ethics codes.
Another voice message was allegedly sent to Pique from Rubiales once the deal had been agreed.
"Well done Geri and I'm not talking about your great game and goal yesterday," Rubiales reportedly said.
"I'm referring to the fact that the agreement is signed with Saudi Arabia.
"Thanks for everything and I'm here for whatever you need."
That message was sent in September 2019, with the first edition of the tournament in Saudi Arabia held the following January.
Real Madrid won the trophy, with Atletico Madrid, Valencia and Pique’s club Barcelona also competing.
