The agent of Jan Vertonghen admits he's fielding big interest for the Tottenham defender.

The 32 year-old Belgium international comes off contract in June and is yet to seriously discuss new terms with Spurs.

Agent Tim de Mul revealed: “We don't have an agreement at the moment, but I don't exclude anything.

"We consider everything.

"There is a lot of interest for Jan, certainly as a transfer-free player, but Tottenham also remains an interesting option for us. The door is still open."
