"So far, there have only been speculations," the former Real Madrid winger told Sport. "There is nothing concrete and I haven't received any offers.
"The only thing I can say is that Barcelona are a great team and everybody would love to play for them."
Robinho did, however, insist he remains 'comfortable' with his decision to swap Madrid for Manchester.
He said: "I left because I was not happy. I do not regret the decision and I'm comfortable at Manchester City."
