MILAN, Sept 19 (Reuters) - AC Milan vice-president Adriano Galliani says the European champions would allow their out-of-favour Brazilian striker Rivaldo to leave if he asked them for a move.

Rivaldo has not started for Milan so far this season and Italian and Brazilian media have speculated that he is unhappy at the club.

Galliani, who runs Milan on behalf of club president and Italian Prime Minister Silvio Berlusconi, said there was no problem between the former Barcelona forward and his club but added they would not stand in his way if Rivaldo asked to leave.

"There is no Rivaldo problem," Galliani said on Friday in comments reported by Gazzetta dello Sport's website.

"If he is happy to stay with us then he will stay, if however he asks to go then we will let him go.

"At the moment he hasn't asked me for anything," said Galliani.

Brazilian World Cup winner Rivaldo joined Milan from Barcelona at the start of last season but has struggled to make an impact at the San Siro.

Although Milan won the Champions League last season, Rivaldo played little more than a bit-part in the latter stages of the campaign and watched the victory over Juventus in the final from the bench.

Rivaldo did not feature in Milan's 1-0 win over Ajax on Tuesday as they opened their European title defence, having dropped further down the pecking order since the arrival of fellow Brazilian Kaka.

The forward has a contract with Milan which runs until June 2005.
