Claudio Ranieri admits he's unsure if Roma will sign permanently Bayern Munich striker Luca Toni.

Roma have been linked with a bid for Flamengo striker Adriano, which could put an end to Toni's time in the capital.

Ranieri said: "Even if I were to know something about Adriano, I certainly wouldn't say so. I can say that I always accept bets and who knows me knows how I work.

"There are many players who I would like: Villa, Milito, Eto'o. They are all important.

"I don't know about Toni. We'll see."
