Former AC Milan and Real Madrid midfielder Kaka has revealed which side of the Lionel Messi-Cristiano Ronaldo argument he is on.

The Brazilian arrived at the Estadio Santiago Bernabeu the same summer as Cristiano, but he instead opted to go for Messi.

“I played with Cristiano and he’s really amazing, but I’ll go with Messi,” Kaka said during an Instagram LIVE Q&A for FIFA’s channel.

“He’s a genius, a pure talent.

“The way he plays is incredible.”

However, Kaka made sure to praise the Portuguese forward.

“Cristiano is a machine,” he stated.

“It’s not just the way he’s strong, powerful and fast; he’s strong mentally.

“He always wants to win and play. To be the best.

“For me, that’s the most incredible thing he has.

“In the history of sport, they [Messi and Cristiano] are definitely in the top five.

“We are very lucky to have been able to see both of them.”

When asked who was the Brazilian he played with or against, Kaka was clear.

“I played alongside some greats in my career, but Ronaldo [Nazario] was the best,” Kaka noted.

“After that, I’d say Ronaldinho, who I was able to play against many times, both at Milan and Real Madrid.”
