The 32-year-old is thought to have been "outraged" by what he feels is unfair treatment by Spanish tax authorities, making him determined to quit the club and the country.
Now facing a lawsuit, Ronaldo, who is one of the world's most expensive footballers, is accused of de-frauding the Spanish tax system of nearly 15 million euros.
Florentino Perez insists Real Madrid are not contemplating Cristiano Ronaldo's departure this summer. He made just more than 250 appearances for the Red Devils in all competitions, scoring 113 goals in the process.
Perez first became Real president in 2000, seeing off incumbent Lorenzo Sanz by promising to lure Luis Figo from bitter rivals Barcelona, which he quickly delivered on by bringing the Portuguese to the Spanish capital for a then world record fee of 62 million euros.
Ronaldo could reunite with head coach Jose Mourinho and work together to accomplish what they failed to do in Real Madrid - win the UEFA Champions League. As for what Real would expect to receive in return for selling Ronaldo, Metro says "a €150m (£131m) bid could be enough".
The rumours come after the sporting hunk hinted at leaving "dream club" Real Madrid, following accusations of tax fraud.
Real Madrid president Florentino Perez has revealed he has not held talks with Cristiano Ronaldo and says the uncertainty surrounding the player is "very strange". He is one of those players who stands out, and whenever there has been a problem we have solved it.
Ronaldo has ignored pleas from Real boss Zinedine Zidane to reconsider his position. He would cost a lot more than the £80 million Manchester United got for him in 2009, but the team has the financial muscles to pull it off.
"Even though he would make more of an impact at other teams that don't have such an impressive commercial appeal".
"I've seen very little of Mbappe, I know he's 18, a very good player, but for the moment he's a Monaco player", Perez said in an interview on radio station Onda Cero.
