Ronaldo is among the frontrunners for the prestigious prize, which considers performances during the calendar year, as well as "overall behaviour on and off the pitch".
It was a forgettable bow for Ronaldo, who was shown a straight red card following an inconspicuous coming together with Valencia defender Jeison Murillo in an off-the-ball incident.
Meanwhile, Real president Florentino Perez has opened up on Ronaldo's departure.
Speaking to DAZN sports streaming network, 24-year-old Can was quoted as saying: "I just found out it (the red card) was because he pulled Murillo´s hair".
The Portugal captain fell to the ground in disbelief and then yelled into the air in frustration, although Juventus overcame his dismissal thanks to a pair of Miralem Pjanić penalties.
Ronaldo's time in Spain was trophy-laden, in which he won the Champions League four times and La Liga title twice, while he is also the club's all-time leading goal-scorer.
The season people were expecting from the 5- time Ballon d'Or victor for Juventus has been everything but usual.
THE Italian newspaper Tuttosport has called for referee Felix Brych to be dropped by Uefa after his sending-off of Cristiano Ronaldo in Juventus' Champions League win at Valencia on Wednesday night, branding the German's display at Mestalla "shameful".
UEFA's control, ethics and disciplinary panel will meet next Thursday to review the incident, which was one of the main talking points after the opening set of Champions League fixtures.
"From that point of view, it's hard to think that he will only get a one-match ban". "I can only say that VAR would have helped the referee make the right decision", Allegri said.
"But we realise the suspension would be absurd, so no suspension and let's immediately introduce VAR in the Champions League".
"He was sad after the match, very sad, and we were all sad for him".
"And if that's the case, unfortunately, we won't see Ronaldo at Old Trafford".
