Chelsea are being strongly linked with a move for AC Milan forward Pato.
Reports in Italy claim the clubs are in advanced talks with Chelsea manager Carlo Ancelotti prepared to sanction a deal worth £18m plus Didier Drogba in part-exchange.
Neither club has commented about the transfer talk but Ancelotti is a known admirer of the Brazilian player from his time in charge at the San Siro and he is looking to freshen up his Chelsea squad.
