We have the same rumor every 2 months, according to click baiters journalist Ronaldo already left Juventus 10 times in 3 years.
And even if he will leave Juventus have a "potential fire of 110m €" to make a shot to buy a top player with the savings in the balance.
PSG can bring salary to Ronaldo but to say they can satisfy all needs of CR7, they don't. Playing for PSG probably won't help CR7 much in personal awards.
I think he will stay in Juventus as long as Pirlo can manage his works and keep Juventus being competitive for titles and if Pirlo can bring Juventus to Champions League finale, CR7 will stay in Turin.
Ronaldo are 35yo, only PSG or Manchester City can pay all this money for a player of this age. IF Cristiano like win another Champions League, need change team, Juventus win last Champions in 1996 and now with Pirlo is really hard think about winning. For me Ronaldo can play well another 3 years, if aspires to win another champions, he must change team. I think play another 2 years with Juventus and after go to close career in China or USA
