Tottenham will turn their attention to agreeing new contracts with Jan Vertonghen and Nacer Chadli when they finalise talks with Christian Eriksen.

As revealed by Football Insider on Sunday, Eriksen is close to agreeing a five-and-a-half-year deal that will lift his salary to around £80,000-a-week.

A source has told Football Insider that Spurs are also keen to reward Belgian duo Vertonghen and Chadli weeks after tying a third Belgium international, Mousa Dembele, to a new agreement.

Vertonghen, 28, is currently sidelined with knee ligament damage that could keep him out for two more months but he has been excellent this season alongside Toby Alderweireld in the centre of defence.

His deal expires in the summer of 2018, which is the same time as Chadli, who has showed some signs of a return to his best since returning before Christmas from a two-month injury absence.

Spurs have previously cashed in on their prized assets, such as Dimitar Berbatov, Luka Modric and Gareth Bale, but manager Mauricio Pochettino wants to keep the current squad together and develop a youthful and hugely promising group of players.

Other than simply keeping the squad together for Pochettino, Tottenham chairman Daniel Levy is well aware that Vertonghen and Chadli – as well as Eriksen – will be more valuable if they are tied to longer contracts.

In other Tottenham news, Watford manager Quique Sanchez Flores is shock by how much Spurs have improved in the six weeks between their two fixtures.
