A rejuvenated Kaka scored one goal and had a hand in two more as nine-times European Cup winners Real Madrid thumped Ajax Amsterdam 3-0 to seize control of Champions League Group D.
Portuguese forward Cristiano Ronaldo opened the scoring in the 25th minute at the Bernabeu, finishing off a sweeping breakaway move. Brazil playmaker Kaka and France striker Karim Benzema then struck either side of halftime.
"It was a good win and puts us in a good position in the group," said Kaka, who looked back to his sparkling best.
In the other game in Manchester City's group, Napoli's "Three Tenors" proved too much to handle in a 2-0 win over Villarreal that marked the Italian club's first home game in Europe's top competition since the heyday of Diego Maradona.
Marek Hamsik scored for Napoli in the 14th minute and Edinson Cavani doubled the lead with a penalty three minutes later as Ezequiel Lavezzi played his part in both goals.
Inter Milan revived their campaign under new coach Claudio Ranieri after quickly recovering from throwing away a two-goal lead in a 3-2 win at CSKA Moscow. Substitute Mauro Zarate scored a 79th-minute winner moments after CSKA Moscow had equalised.
