Brazilian midfielder, who scored in his team's victory at La Romareda, continues to insist that his future lies in the Spanish capital amidst report of a move away
The Brazil international came on for Mesut Ozil in the 78th minute at La Romareda and found the target just four minutes later.
Kaka has been continuously linked with a move away from the Santiago Bernabeu this summer, with Italian giants Inter and AC Milan and French big-spenders Paris Saint-Germain all reportedly interested in the 29-year-old's signature.
However, the 2007 Ballon d'Or winner himself has always insisted that he has no plan to leave the Spanish capital and reiterated his stance following Sunday's victory.
"I'm happy with our start to the league; this day is important to all of us," Kaka is quoted as saying by Madrid's official website. "I've always been clear about wanting to be successful at Real Madrid.
"[Coach Jose] Mourinho said he counts on me and I hope to make good use of the chances I get. We all enjoyed ourselves and we're all very happy with the match."
Madrid's arch-rivals and defending Spanish champions Barcelona are in action on Monday when they host Villarreal at Camp Nou.
