The 24-year-old has been strongly linked with a move to Premier League outfit Tottenham Hotspur, while Real Madrid have also been rumoured to be attracted to the player since the appointment of Carlo Ancelotti as their new coach.
However, Paulinho, who was one of the stars as his country won the Confederations Cup on Sunday, insists that nothing has been sorted about a summer transfer yet.
"I can't give you any details at this moment, it's impossible," Paulinho told Gazeta Esportiva when asked about his future.
"I will still talk with Corinthians and with my agent before making a decision. When I decide, I'll tell everyone. I will only talk about this from tomorrow (Monday)."
It has been reported that Spurs will pay a £17m transfer fee for the Brazilian.
