Ronaldo has been heavily linked with a move away from Man United this summer.
The Portugal international has been linked with a move to Chelsea, Bayern Munich, and a club in Saudi Arabia.
The five-time Ballon d’Or winner has already informed Man United that he wants to leave Old Trafford should the club receive any suitable offer from him this summer.
Ronaldo is keen to play Champions League football next season.
However, according to football transfer expert, Fabrizio Romano, Chelsea have now taken a final decision not to sign Ronaldo because their manager, Thomas Tuchel, doesn’t want the former Real Madrid and Juventus star at Stamford Bridge.
He added that the Blues are now focused on other different deals.
“Thomas Tuchel has decided against Cristiano Ronaldo signing, as things stand. Jorge Mendes had talks with Todd Boehly but final decision has always been up to the manager,” Romano tweeted on Thursday.
“Chelsea are now focused on different deals – Tuchel isn’t keen on signing Cristiano.”
