AC Milan vice-president Adriano Galliani fears the club will fail in their bid to sign striker Emmanuel Adebayor from Arsenal.

Galliani maintains the 24-year-old is the club's only transfer target this summer but is worried they will not convince Arsenal to let him go.

The Italians are believed to be prepared to offer as much as £32million for the Togo international, who has three years left on his deal.

Galliani says it the length of his contract at Arsenal that has left Milan powerless and he is on the verge of conceding defeat. The Milan official said: "Adebayor has a contract, I'm always a pessimist by nature. Look at last year when Real Madrid said Kaka was theirs. If the club don't allow you in there's nothing you can do.

"If he's at the end of his contract then his wishes are important, but if not and there's a contract and the club who owns him says no, then it's no. At the moment, it's no.

"Does it depend on [Arsene] Wenger? He's the Arsenal manager, a representative of the club, and at the moment the club are not selling.

"Everything depends on Arsenal, but when a club says their player is indispensable there's not a lot that can be done.

"Of course things could always open up but at the moment I must keep to Arsenal's official line and that is that for the moment there is no possibility of negotiating."

It appears AC Milan had no choice but to go for Adebayor after Galliani was told another of their targets, Chelsea's Didier Drogba, was not available for transfer.

He added: "At the moment there is only one deal in motion. Chelsea say Drogba is not for sale."
