But Ron could still snub Roman Abramovich and choose to go elsewhere. If Chelsea agree a fee with Barcelona, the Brazil World-Cup winner could be unveiled at the end of the season.
Ron, 27, would be the highest-paid player ever on a massive £223,000 a week - £88k a week more than Blues skipper John Terry.
Chelsea will NOT have to pay Ronaldinho's £85m get-out clause after his row with Barca - but they would still have to cough up a world-record £70m.
Ron's current contract has three years to run and is worth around £135,000 a week. AC Milan are also interested but will not be able to match the Blues' offer.
