Robinho joined the Premier League side from Real Madrid for a record fee of £32.5million last summer.
The Brazilian scored 14 goals for City in the Premier League last season.
“So far, there have only been speculations,” he 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.”
He added on his move from Real: “I left because I was not happy. I do not regret the decision and I’m comfortable at Manchester City.”
