Los Blancos currently sit third in La Liga, just one point from first position, while they are into the latter stages of the Copa del Rey and the Champions League.
"We are playing well and we feel confident. We have to improve in some areas, but it was a great match," Ronaldo told the club's official website following the 2-0 victory over Granada.
"The team looks good and we are getting better all the time. Towards the end of the season I am convinced that things will keep getting better."
The capital outfit have kept seven clean sheets in their last seven matches in all competitions, while they have not been beaten since losing to Barcelona at the end of October.
