Tottenham are close to tying Christian Eriksen and Jan Vertonghen to new contracts worth a combined£40.5million, Football Insider sources understand.

Spurs are in talks with the pair about improved deals as they work on a round of contracts for their key players.

Eriksen, 24, has confirmed he will sign a Tottenham extension after being convinced by the club’s ambitions.

Football Insider revealed in January that Eriksen had reached an agreement in principle on a new five-year deal worth £22.9million.

The attacking midfielder, whose current deal expires in 2018, has indicated to the club he will commit to a deal that will lift his salary to £80,000-a-week and run until 2021.

Vertonghen, 28, is closing in on a comeback after two months out with knee ligament damage but he is a mainstay of the team and has been outstanding this season alongside Toby Alderweireld in the centre of defence.

His deal expires in the summer of 2018, but Spurs want to extend the deal until 2020 and lift his salary to around £75,000-a-week in a package worth a total of £17.5million.

Exacting demands: Eriksen has been a key player under Pochettino this season

Target men: Pochettino is keen to tie Spurs’ key players to long-term deals

Eriksen was the subject of strong interest from Manchester United last summer but Spurs had no desire to cash in on a player who has been key to their resurgence under Mauricio Pochettino.

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 the likes of Vertonghen and Christian Eriksen will be more valuable if they are tied to longer contracts.
