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

The Brazilian, who has barely played for bitter city rivals Inter in the last two seasons after a dip in form, joined Milan on Monday on the last day of the January transfer window.

'I really don't understand it,' the Italian prime minister told Jerusalem's Italian community, sources at the meeting 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.
