Cristiano Ronaldo told a Spanish judge Monday that he has "never tried to avoid taxes."

The Real Madrid forward, who is from Portugal, was questioned to determine whether he committed tax fraud worth almost 15 million euros ($17.5 million). Ronaldo spent more than 90 minutes answering the questions of investigating judge Monica Gomez.

According to a statement released by his public relations firm, the 32-year-old Ronaldo told the judge: "I have never hidden anything, and never tried to avoid taxes."

Judge Gomez took Ronaldo's testimony as part of an investigation to determine if there are grounds to charge him. The session at Pozuelo de Alarcon Court No. 1 on the outskirts of Madrid was closed to the public because it is part of an ongoing investigation.

In June, a state prosecutor accused Ronaldo of four counts of tax fraud from 2011-14 worth 14.7 million euros ($16.5 million). The prosecutor accused the Portugal forward of having used shell companies outside Spain to hide income made from image rights. The accusation does not involve his salary from Real Madrid. Ronaldo denies any wrongdoing.

"Spain's Tax Office knows all the details about my sources of income because we have reported them," Ronaldo told the judge, according to his statement. "I always file my tax returns because I think that we should all file and pay our taxes.

"Those who know me know that I tell my consultants that they must have everything in order and paid up to date because I don't want trouble."

Both before and after his court appearance, Ronaldo used an alternative entrance to avoid a large swarm of more than a hundred journalists from Spain and aboard gathered near the main door to the court.

Court officials had said that either Ronaldo or his lawyer would speak to the media after he saw the judge, but instead the player's spokesman, Inaki Torres, stepped up to the temporary podium in front of the courthouse to announce that Ronaldo "was on his way home."

The prosecutor said in June that Ronaldo used what was deemed a shell company in the Virgin Islands to "create a screen in order to hide his total income from Spain's Tax Office."

The prosecutor accused Ronaldo of declaring 11.5 million euros ($12.8 million) earned from 2011-14 in a tax return filed in 2014, when the prosecutor said Ronaldo's real income during that period was almost 43 million euros ($48 million). It added that Ronaldo falsely claimed the income as coming from real estate, which "greatly" reduced his tax rate.
