AC Milan president Silvio Berlusconi is coming under pressure from fans over the likely sale of Kaka.
The Ultras, who have already shown their anger against the Board in recent weeks, are currently protesting in front of Milan's headquarters.
The fans are also claiming they will vote against Silvio Berlusconi at the next elections if Kaka leaves. "I will vote Podestà (Berlusconi's candidate) only if we keep Kaka," claim several placards.
The group of around 300 are being controlled by local police who, despite the tense atmosphere, are reporting no security problems.
The banners send clear messages to the Rossoneri hierarchy. "If you sell Kaka, you sell the club", "President: before lots of honours, now disappointment only" and "Who sells Kaka will pay for it" are some of the other slogans.
