The Belgium international is happy that his performances for Spurs have caught the attention of the Liga 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 they supposedly see Vertonghen as a useful addition to their squad, much to the Belgium international's satisfaction.
"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."
The 27-year-old has a contract with Tottenham until the summer of 2016, but the Premier League side have offered him a new deal until June 2019.
Vertonghen joined Tottenham from Ajax in the summer of 2012 and has consistently been a key player at the Londoners.
