His former Real Madrid teammate Karim Benzema, ex-Manchester City winger Riyad Mahrez and N’Golo Kante, among many others, have moved to Saudi clubs.
Authorities in Saudi Arabia also tried to sign Kylian Mbappe, who turned down their advances.
Not to mention Lionel Messi, who had a spell at PSG following his departure from Barcelona.
Mbappe still operates in France with Paris Saint-Germain, having been the subject of intense transfer speculation as he enters the final six months of his current deal.
Ronaldo calling the Saudi Pro League ‘more competitive’ could stem from the fact that PSG have won nine league titles since the 2012/13 season.
Only AS Monaco and Lille have managed to break up PSG’s dominance in that period.
The French giants currently sit at the top of the table, eight points clear of second-placed Nice.
As for the Saudi Pro League, Al Hilal are seven points ahead of Ronaldo’s Al Nassr.
