Kaka believes there is more to come from Real Madrid despite the club winning their opening four Primera Division matches.
The midfielder scored his first Real goal from the penalty spot as they defeated 10-man Villarreal 2-0 at El Madrigal on Wednesday to maintain their impressive start to the season and ensure coach Manuel Pellegrini enjoyed a happy return to his former club.
The club from the capital are level on points with Barcelona, who beat Racing Santander 4-1 away 24 hours earlier, at the top of the table.
However, despite their 100 per cent start to the campaign, Kaka insists there is still room for improvement.
"I'm very happy with the win, although we can still improve," he said. "To play how we want takes time, but I think we are on the right path."
The former AC Milan star also revealed his delight at finally opening his Real account after going four games without finding the net.
"I'm happy to have scored my first goal," he added. "It's been a great joy and I think I'll score more, but the most important thing is that the team won.
"When I scored, all my team-mates congratulated me. This shows that this team is very united, and my joy is the joy of the whole team."
Record-breakerOne player who is having no trouble finding the net for his new club is Cristiano Ronaldo and the Ј80million man made it seven goals from five games in all competitions after his solo strike in midweek.
The Portuguese star became the first Real player to score in all four opening league fixtures but the former Manchester United ace admitted that the Villarreal match was a hard-fought affair.
"It was a very difficult game against an opponent who have caused us many problems," he stated.
"We were able to score in the opening minutes and this is always important, but the key thing is that we've been able to take away the three points.
"We've had to work hard because they've put us under pressure from the start, but little by little we warmed up and we were able to play how we like."
