The father of AC Milan midfielder Kaka is expected in Italy to discuss his son's possible move to Manchester City.
City are reported to have offered more than £100million for the Brazil playmaker plus a record-breaking salary and Bosco Leite, who acts as his son's advisor, will meet a delegation of Milan officials to clarify the situation.
Noises coming out of the San Siro over the weekend suggest the Serie A giants are willing to negotiate a transfer.
Milan's general manager Adriano Galliani said: "The future of Kaka is not already set in stone. We still have to evaluate, think hard and decide.
"We are in a particularly difficult time with financial problems all over the world and those spread to football.
"What has changed from a year ago? Quite simply, the world is worth half of what it was. Things have changed.
"Unfortunately football is built in a certain way so now you cannot carry on without the cheques from a patron as other clubs keep on raising the financial bar."
And coach Carlo Ancelotti admitted he had already contemplated life without the 2007 world player of the year, adding: "If he were to leave, I would be very sorry. If things were to change, then I would have to consider a team without Kaka.
"We as a club have always worked together to create a team and that is precisely what will happen after this affair."
City manager Mark Hughes, though, warned that any deal is a long way from being completed.
"We are a million miles away from actually concluding the deal. The scale is large and there are too many elements to it.
"It's not a case of talking to the club, talking to the boy and getting the deal done in 24-48 hours. You have to give it the time that it deserves."
Manchester City manager Mark Hughes has hit out at critics of his club's audacious move and defended City's position.
"I have been a little disappointed about some of the reactions to the prospect of a fantastic player coming to City," Hughes told the Manchester Evening News.
"There are some elements of the media who are talking about a deal and how much Kaka is going to earn when those things are a long way from being talked about.
"It is being said that the player is going to get a level of wealth that some people are saying is obscene when the club are not even having those talks yet.
Kaka put his hand to his heart, waved emotionally and applauded the fans after Saturday's 1-0 win over Fiorentina at the San Siro.
"The fans showed a great gesture of affection to Kaka," Galliani added to Sky Italia. "There are no replacements for Kaka because he is unique."
Around a thousand AC Milan fans protested at the club headquarters on Monday. Angry supporters chanted and held up banners in the pouring rain while blocking a main road outside Milan's city centre offices.
