The football phenomenon has had quite the impact since returning to Manchester United for an initial £12million fee, scoring three times already in just two matches.
But his influence hasn't just been shown on the pitch, as current United reserve keeper Lee Grant explained to talkSPORT earlier this week.
Grant revealed that not one player ate dessert at dinner after they saw Ronaldo eating quinoa and avocado.
He said: "To give you one instance of the impact he is having on the group right. This was Friday night in the hotel.
"So, as you guys will be aware, you finish your dinner and usually on a Friday night you've got some cheat stuff out.
"You've got some apple crumble and custard or you've got a bit of brownie and cream or whatnot.
"I tell you now, not one player touched the apple crumble and custard, not one player went up for that brownie because everybody was sat down.
"One of the lads said to me, "What has Cristiano got on his plate?"
"So we were having a little goosey gander at what he has got and obviously it is the cleanest, most healthy plate you can imagine.
"And it just cracked me up how not one single player dared get up and have that junk food that was laid out."
In light of the comments,Deeney joked he'd do everything Ronaldo did if it meant he performed to the same level as the 36-year-old.
"If I saw Ronaldo eating horse s*** for a pre-match meal, I'd eat horse s*** too!," the Birmingham striker told The Sun.
Ronaldo's insanely toned figure stems from his meticulous diet.
The former Real Madrid man eats often but in little quantities, consuming around six meals a day spaced out at 3-4 hour intervals.
He does this to meet the high nutritional demands of being a top footballer and support the fast metabolism athletes have.
With a nutritionist by his side wherever he goes, Ronaldo has been following this diet since his days at Real.
You wouldn't be surprised if he's still playing his 40s.
