The Brazilian star scored in the victory against the Aragonese outfit on Saturday, and went on to express his contentment with his current situation in the capital after the match
The 29-year-old has been in and out of the XI at the Santiago Bernabeu this season, triggering speculation over his future at the club, but after a fine goalscoring display against the Liga strugglers, he spoke of his satisfaction at being back in contention.
"I feel good, I'm playing well and I am happy," he said. "The Bernabeu helps us a lot and we can create an impact."
However, Kaka admits Madrid's performance against Zaragoza was not perfect by any stretch of imagination, but hopes he and his fellow team-mates enjoy a productive week on the training ground to rectify their inefficiencies.
"We can not always leave a trace, and we sometimes concede goals both at home and away - these are the things that require improvement," he continued.
"We have a week to work in training and prepare many things for the game against Getafe."
Real Madrid have provisionally moved eight points clear of Barcelona, who play Villarreal later in the evening.
