That is the view of former Everton and Australia star Tim Cahill, who admits that not everyone will agree with his theory.
Cristiano Ronaldo and Lionel Messi have both won five Ballon d’Or trophies, but missed out to Luka Modric in 2018.
It is likely that one of the megastars will retain the trophy this year, and Cahill reckons the Portugal skipper should take home the award.
Cahill told Alkass Sport: “He left Real Madrid, went there and had such a massive impact on another league.
“I’ve never seen another player do it at Man United, Madrid for so many years.”
Ronaldo played for Manchester United from 2003 until 2009, scoring 118 goals in 292 appearances and winning seven major trophies.
At Real Madrid he hit his peak, scoring 450 goals in 438 games and winning another eight trophies.
The 34-year-old has hit the ground running in Italy but his goal return has faltered slightly, with 28 goals in 43 appearances.
Although his season at Juventus marked his lowest goals return since 2009, Cahill has been impressed by Ronaldo’s overall performances.
He continue: ”I know he didn’t win the Champions League but he has such an impact in any club.
“If you can take players and put them somewhere at his age.
“I know people won’t agree, I just appreciate his professionalism.”
Ronaldo joined Juventus last summer and has gone on to win both the Supercoppa Italiana and Serie A titles.
For manager Massimiliano Allegri however, those two triumphs were not enough to buy him another year as boss, with the club deciding to appoint a new man ahead of next season.
Beside a photo of the pair together, though, Ronaldo wrote an impassioned message hailing the departing gaffer, saying: “Thank you Mister!
“We lived a single year together but it was awesome because besides being a great coach you are a great man. It’s been a pleasure working with you!”
