AC Milan owner Silvio Berlusconi lambasted his own club and chief executive Adriano Galliani for signing Internazionale winger Mancini on loan.

"I really don't understand it," the Italian prime minister said.

"He is another creative player when we need someone who can finish off moves. He's not played for two years. I don't agree with getting him and I've told Galliani."

Berlusconi rarely clashes publically with trusted lieutenant Galliani, who has run Milan on his behalf for over 20 years, but often comments on the Serie A club's formations and fortunes.
