Ronaldinho's brother Roberto de Assis, who is also his agent, said: "Will a move be agreed in December? You'll have to ask the club.
"I can't receive offers - it's down to Barca to receive and consider offers. I haven't spoken to anyone.
The Sun says De Assis has made no attempt to hide his delight that all the talk around the Nou Camp was Chelsea are determined to sign Ronaldinho, 27.
The playmaker is fed-up with Barca president Joan Laporta for failing to deliver a promise made 18 months ago to hand him a new contract until 2014.
Ronaldinho is now prepared to buy out the last two years of his existing deal under FIFA rules for around £14m.
Barca value Ron at £50m - but they would have to slash that fee if he is sold in January.
A group of Nou Camp directors are urging Laporta to cash in now.
Ron has been dropped from the starting line-up for the last two games.
He has also been hauled off eight times from 11 starts.
