The Tottenham defender's representative says he is attracting plenty of attention after two years in London, but he refused to confirm whether or not the Blaugrana are interested
The Blaugrana are understood to be in the market for a centre-back after Carles Puyol's retirement and with the threat of a suspended transfer ban hanging over them, and have already made several other signings this summer.
Vertonghen was disappointing in his second season at White Hart Lane but has nonetheless been linked with a move to Camp Nou and Mustapha Nakhli, his representative, says that plenty of heads have been turned.
He told Het Nieuwsblad: "Several teams are interested in Jan. I cannot confirm or deny whether Barcelona are one of them.
"Tottenham is not a small club. It’s too soon to give them an answer. Several clubs have registered their interest in Jan. We'll see."
Vertonghen joined Spurs from Ajax in 2012 and has since made over 80 appearances for the North London side.
Also capable of playing at left-back, he helped Belgium to the quarter-finals of this summer's World Cup before they were eliminated by Argentina.
