The Belgium international had been tipped to sign a new long-term deal with the north London club before the new Premier League season.
However, Vertonghen has been linked with the Catalan side and Liverpool in recent weeks, although the Reds have snapped up Dejan Lovren on Sunday.
And 27-year-old is adamant that there is no truth to speculation suggesting the former Ajax captain could move to Barcelona this summer.
“It’s certainly flattering when a big club like Barcelona show an interest in signing you,” Vertonghen told Sporza.
“It’s confirmation that you are on the right track.”
He added: “They say ‘when there’s smoke, there’s fire’, but there’s no fire for now.”
Vertonghen has scored four goals in 57 Premier League appearances following his £10m move to White Hart Lane from Ajax in 2012.
