Former AC Milan idol Kaka has added fuel to the fire ahead of Real Madrid's Champions League clash against the Italian giants on Wednesday.
The Brazilian, who joined the Madrid side in a multi-million pound deal in the summer isn't sure why the Rossoneri have struggled in recent years after failing to keep up with European super powers such as Barcelona and Manchester United.
Speaking at a press conference, Kaka said: "I think Real Madrid are slightly bigger throughout the world because people follow them everywhere.
"That's the greatest difference between both teams.
"Milan have always been a strong team in Italy and in Europe. That has changed in the last two years.
"They haven't been able to beat big teams and perhaps their signing policy has changed."
