Flamengo won't give up on AC Milan's Ronaldo
Hinrichsen said: "We need financial support to present a concrete offer to Ronaldo. I think that as a club, everything will be settled by the end of the week.
"Companies seem interested in the project, but as yet nothing concrete has arrived. We haven't addressed the financial issue, which is the most difficult."
Flamengo president Kleber Leite also said: "We are putting together a proposal to present to the player."
