Tottenham want to announce new contracts for Christian Eriksen,  Jan Vertonghen and Erik Lamela at the same time, Football Insider sources understand.

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

A source close to the Tottenham boardroom has told Football Insider that the club are hopeful the deals will be completed before the summer and they are planning to announce them together.

Eriksen, 24, has strongly hinted 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, made his comeback last weekend after two-and-a-half months out with knee ligament damage and slotted in seamlessly alongside Toby Alderweireld in the centre of defence.

Manager Mauricio Pochettino said it was an “easy” decision to reinstate the Belgian even though Kevin Wimmer had deputised impressively for 15 matches.

Vertonghen’s 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.

Lamela is also set for a contract extension in the wake of comfortably the best of his three season at White Hart Lane.

The Argentine, 24,  has two years remaining on his current deal, which was signed when he joined from Roma for £30million in 2o13.

Spurs have previously cashed in on their prized assets, such as Dimitar Berbatov, Luka Modric and Gareth Bale, but 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, Eriksen and Lamela will be more valuable if they are tied to longer contracts.

In other Tottenham news, it has been reported that Bayern Munich have a “crush” on a 22-year-old Spurs ace.
