The Belgium international is happy that his performances for Tottenham have caught the attention of the Catalan giants, but stressed no transfer is in motion yet
The Catalans - who recently signed Jeremy Mathieu from Valencia - are keen to further strengthen their defence ahead of the 2014-15 campaign and reportedly see Vertonghen as a useful addition to their squad.
Earlier this week the 27-year-old revealed he has been offered a new five-year deal by Tottenham and insisted he is happy to stay at White Hart Lane, but he admits he is flattered by interest from Barcelona.
"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."
Nevertheless, Vertonghen has made it clear that a transfer is still far away at this stage as the Camp Nou side are yet to have made an approach for him.
"They say 'when there's smoke, there's fire', but there's no fire for now."
Vertonghen joined Tottenham from Ajax in the summer of 2012 and has consistently been a key player at the Londoners.
