Juventus did not reply to a request for comment on Tuesday night.
A report in the Spanish press recently said that Ronaldo's release clause has been lowered from the obscene figure of €1bn to just €120m, which for a player of his quality actually represents decent value in the current market, despite him being 33.
The newspapers cited the TV report in their own discussions of a potential transfer, but did not confirm that the deal has already been agreed.
Cristiano Ronaldo tight-lipped on future after World Cup KO
Remarkably, neither Ronaldo nor Messi have managed to score a single goal in a knockout tie in 4 World Cups going back to 2006. In fact, three statistics show just how bad Ronaldo was during his side's loss to Uruguay.
Juventus now appear ready to welcome Ronaldo to Turin with welcome arms.
Ronaldo, who scored four goals at the 2018 FIFA World Cup as Portugal crashed out at the round of 16, hinted at leaving the La Liga club shortly after their historic third successive UEFA Champions League title win last season.
The claim comes from French journalist Baptiste Ripart - the man responsible for breaking news of Antoine Griezmann's contract renewal at Atlético Madrid and their signing of Thomas Lemar. "I am not of course sure if he wants to leave Real Madrid or not but maybe he wants another adventure, in another league, let us see what happens".
Mbappe became the second-most expensive player in history when he joined Paris Saint-Germain on a permanent deal from Monaco for £128m earlier this year.
