Sevilla have confirmed that Sao Paulo have tabled an offer for Brazil international Luis Fabiano.
Fabiano has been unsettled since leading the line for his country at last summer's World Cup finals in South Africa.
The striker agreed a contract extension until 2013 in August but his campaign has been dogged by injury and inconsistency.
Sevilla have not decided whether to part company with the 30-year-old and sporting director Ramon Rodriguez insists the club will not be rushed.
"They (Sao Paulo) have made us an offer which we are evaluating and studying. It's complex and needs time," explained Rodriguez.
"I don't know what will happen. To move forward it needs to be an offer that satisfies us, something which as it stands, doesn't.
"It's a purely economic offer, and there is no player or swap involved."
"He's a difficult character. Sometimes he pulls one way and then pushes the other, but he has always been like that. We have enjoyed his character and we still do.
"The possibility of him going to Brazil has been knocking around for some time, but the decision will be Sevilla's and no one else's."
