"No, maybe he misses me!"
The Portuguese star then also praised Lionel Messi and his performance while saying "However, if he is happy there, I respect him".
In a low profile clash at the Santiago Bernabeu, the defending champions Real Madrid took on CSKA Moscow.
The Swede replied, "Now we know it was Perez who was competing with Messi on Ballon d'Ors, not Ronaldo." . This was the first year when 16 group-stage places were guaranteed for the Big 4 leagues in Europe - Spain, England, Germany and Italy.
"The numbers do not lie, but do not think that I'm less happy if I do not win". But the Champions League match could be a good occasion for him to put in a good display.
"[I am] disappointed but life goes on and I will still work hard".
"I left my comfort zone and took on this challenge here in Turin".
Ronaldo has scored 11 goals this season, bringing his career total to 584. "In any case, we've made sure we'll spend the holidays in a great mood after tonight's win".
The Champions League holders had been beaten 1-0 in the Russian capital earlier in their Group G campaign, yet they were already assured of going through as pool winners.
"For me it is attractive, I perceive the difference".
"It's very different to Madrid, here it is more of a family". "It has a long history", he said of his decision.
It has been suggested that further deals may be in the pipeline, with a number of Blancos players prepared to follow a former team-mate to Italy.
The average age of Real Madrid's starting XI was their third youngest in the Champions League era.
Though neither won the Ballon d'Or this year - the first time since 2008 - both Messi and Ronaldo have been in their usual fine form at the start of the new season.
"Now I'm 100 per cent sure it was the right option".
