Milan are in the market for a new striker after selling Alberto Gilardino to Fiorentina, while Brazilian ace Ronaldo is still out with a serious knee injury.

"It's no secret we're interested in signing a forward and are studying candidates," Leonardo said.

"Drogba is a fine player and Adebayor is a player I really like. We are waiting for the right time to move."

Milan vice-president Adriano Galliani had said in June that Adebayor was the Rossoneri's "sole transfer target" of the summer, although he later admitted that Arsenal's valuation of the Togolese striker left Milan unable to afford the player.

It has been reported that Chelsea are yet to receive a single offer for the unsettled Drogba, and World Cup-winner Leonardo admits they will struggle to compete financially with the likes of Manchester United, Real Madrid and Barcelona - who are all thought to be interested in the Ivory Coast international.
