Adriano's agent has confirmed that a host of clubs from across Europe are keen to sign the Brazil striker in the January transfer window.
The former Inter Milan front man is currently with Flamengo in his homeland where his goals have helped the club claim the Brazilian championship.
West Ham boss Gianfranco Zola has been linked with a possible move for the powerful striker as he looks to bolster his forward options.
But it appears the Hammers will face stiff competition from elsewhere on the continent for Adriano's services, while he may even remain in South America as he looks to secure a place in Dunga's World Cup squad.
His representative Gilmar Rinaldi told calciomercato.it: "After winning the Brazilian championship I have not spoken to him.
"I can say that I have received offers from Italy, England, Spain and Greece. I have so many offers from Europe.
"Adriano will now take a holiday and then we will evaluate everything. By Christmas, I think it will be decided.
"At the moment, the idea is to remain in Flamengo until the World Cup."
