Toby Alderweireld is in line for a new deal that could see the Tottenham defender double his money.

Though the 28-year-old has a contract that lasts until 2019, Tottenham are aware Alderweireld is attracting attention from home and abroad.

Spurs are not interested in selling the Belgian international, who is on about £50,000 a week.

Tottenham want to offer key defender Toby Alderweireld a new contract at the club

The Belgian centre back's current £50,000-a-week deal does not run out until 2017

Harry Kane and goalkeeper Hugo Lloris are their top-paid players on north of £100,000 a week.

Any agreement with Alderweireld, who was a surprise absentee in the Premier League’s team of the year, is likely to last five years.

His current contract includes an option for Tottenham to take up an additional year.

Activating that clause in 2019 triggers a £25million release clause, though re-negotiations would likely see Tottenham take that out.

Dishing out new deals is a fine balance for Tottenham. They do not want to risk an unsettled squad by having some stars on far greater wages than others.

Meanwhile, Tottenham chairman Daniel Levy will fight to prevent his highly sought-after stars from leaving for direct Premier League rivals this summer.

Spurs are bracing themselves for a flurry of interest in their top players following another excellent season.

Eric Dier is a key target for Manchester United boss Jose Mourinho, while Kyle Walker is wanted by Manchester City. Harry Kane, Dele Alli and Danny Rose also have elite-level suitors.

Regarding Dier and Walker - United and City, respectively, remain hopeful. However, Levy is determined not to do business with any Premier League club this summer.

Even if Levy considers selling an important member of Tottenham’s first-team squad, he would exhaust the option of selling to a foreign club.

The Spurs chairman has a reputation for being one of football’s toughest negotiators, one of the reasons why City have scaled back their interest in Rose and Alli in recent weeks.

But Walker remains firmly on Pep Guardiola’s radar, with City desperate to strengthen at right-back this summer with Bacary Sagna and Pablo Zabaleta set to leave.
