Kaka: Specialist Ronaldo vital to Real Madrid

Kaka has talked up the influence Cristiano Ronaldo will have on Real Madrid's season prospects.

The Brazilian ace said: "Cristiano is very important to us. In many games that are played, it is the set-pieces that will decide them and to have a specialist like him is vital."

"The game against Zurich was complicated, but through one of his free-kicks, the match has been decided. Cristiano can decide the fate of a match at any time."
