Adebayor, 27, appears to have no future at City under boss Roberto Mancini and has made it clear that he favours a return to the Spanish capital, where he went on loan last season.
But flying winger Ronaldo, speaking in the southern Chinese city of Guangzhou, where Real are on a pre-season tour, said: "I don't think that we need to sign another forward. We are happy with the line-up as it is already."
Real, who were again runners-up to fierce rivals Barcelona in La Liga last season, have added Spanish midfielder-striker Jose Maria Callejon to their already hugely impressive array of attacking talent.
They also have French striker Karim Benzema, who has enjoyed a free-scoring pre-season but whose Real career has failed to take off so far, and the prolific Argentine Gonzalo Higuain.
Real coach Jose Mourinho, who has kept a low profile in China so far, last month said he was looking to bring in another forward, but Adebayor -- who has also been linked with Spurs and Bayern Munich -- has remained at City.
Former Manchester United star Ronaldo said it was vital to beat Barcelona when the old foes clash in the two-legged Spanish Super Cup later this month.
"It's an important match because it's the beginning of the season so we want to start well -- it could give us vital impetus to the campaign," the 26-year-old Portuguese star said.
Chinese journalists tried to press him on fatherhood, with one reporter asking him if he ever changed his baby son's nappies.
"Of course, as a father it is normal to change the baby's nappies," an unamused Ronaldo replied in English.
And asked if he might ever return to United or English football, he said simply: "Maybe, why not? You never know."
Real take on local side Guangzhou Evergrande on Wednesday before heading to the city of Tianjin, close to Beijing.
