The Corinthians midfielder is set to keep the north London club sweating until after the Confederations Cup, even though Spurs chairman Daniel Levy is understood to have already agreed a £15million fee with the Brazilian outfit.
Andre Villas-Boas is keen to bring the 24-year-old to White Hart Lane this summer, but now faces competition from his former employers Chelsea, for Paulinho's signature.
"There is an official offer from Tottenham to Corinthians," confirmed the Brazil international after Saturday's 4-2 victory over Italy. "But, as I did when there was an Inter Milan offer, I'll sit and decide with my family before I make any decision.
"I will only do it after the Confederations Cup because it's hard to deal with all these things."
Despite Chelsea's emerging interest, with Jose Mourinho preparing to lure Paulinho to Stamford Bridge, Tottenham remain favourites to sign Paulinho, after Corinthians director of football, Edu, confirmed that negotiations are at an advanced stage.
"The situation is well underway. We have to agree on some details of the negotiation, so I can't say he will leave yet, but the negotiations are good."
Either way, Paulinho looks set to seal a switch to the Premier League - be it to Tottenham or Chelsea - following in the footsteps of his international team-mate Oscar, who moved to west London to join the Blues last summer.
