Chelsea could re-enter the race to sign Paulinho later this year after Inter Milan revealed it would be difficult to sign the Corinithians midfielder this month.
The San Siro side have freed up squad space by selling Wesley Sneijder, while Philippe Coutinho's impending transfer to Liverpool will also reduce their current wage bill.
As such, the 2010 European champions had hoped to firm up their interest in Paulinho but club president Massimo Moratti feels Corinthians' desire to hold on to him could prevent a deal from taking place this week.
"No news on Paulinho," Moratti is quoted as saying on Tuttomercatoweb.com. "It's not a question of money. We believe that the operation might be easier in June because of the player's commitments in Brazil."
Chelsea have also tracked the 24-year-old, with Rafa Benitez keen to sign another central midfielder, but club officials have told the interim boss he will not be permitted to spend again during this transfer window.
