Tottenham are set to extend Jan Vertonghen’s contract until the end of the season after being given the green light today, Football Insider understands.

The Belgium international, who turned 33 last month, has knocked back the club’s offer of a new contract to replace his agreement expiring next month.

But a Tottenham source has told Football Insider that Vertonghen is expected to agree a short-term extension after Premier League clubs voted to allow out-of-contract players to sign until the season finishes.

The governing body announced today that “players can extend their contracts beyond June 30 until the end of the season, but it must be agreed by both parties”.

Clubs and players have been given until 23 June to reach agreements.

Vertonghen is out of contract is six weeks and has already rejected Tottenham’s offer of a one-year deal on reduced terms.

But the club are hopeful of agreeing an extension on the same terms as his current deal.

It would allow Vertonghen, who has publicly kept the door open to remaining in north London, to bring down the curtain on his eight-season Spurs career and potentially end it in style.

The defender is then expected to move to a new club when the transfer window eventually opens, most likely to Italy or Spain.

Vertonghen , who joined Spurs in 2012, has lost his regular starting place this season but has still made 26 appearances in all competitions.

Eighteen of those have come from Premier League starts, with the versatile Belgian slotting in at left-back on a number of occasions
