Tottenham Hotspur are confident that Dele Alli will sign a new contract to commit himself to the club, despite the fact he is in the process of changing agents.

And Spurs and England hope that a fresh deal, with a significant pay rise, will help Alli get back to his very best ahead of next summer’s World Cup.

Alli is being chased by all of the world’s biggest agents after deciding he will leave his long-term representative Rob Segal, when their current agreement expires.

That has fuelled speculation that Spurs could face a fight to keep Alli past this season and may struggle to agree a new contract with the 21-year-old that fits in with the club’s wage structure.

Alli signed a six-year contract, which earns him around £50,000-a-week, last September, but he is well down the list of Tottenham’s best-paid players.

Sources close to Alli fear the situation has impacted on the England international’s performances and behaviour. He missed the World Cup qualifier with Slovenia after being suspended for a middle-finger gesture against Slovakia and was criticised for diving in Tottenham’s victory over Huddersfield Town.

But Spurs are currently preparing a new contract offer and believe they can reach an agreement before he formally changes agent, which might not be until after the World Cup.
