Tottenham chairman Daniel Levy

Frank McAvennie insisted it is “massively important” Tottenham renew terms with Son Heung-min this season.

The former West Ham and Celtic striker, speaking exclusively to Football Insider correspondent Dylan Childs, hailed the relationship the 28-year-old has developed with Harry Kane this season.

As revealed by Football Insider the London club are in advanced talks with the attacker over a new five-year deal worth more than £200,000-a-week.

The deal would take the South Korea international into the top bracket of earners at Spurs alongside Kane and Tanguy Ndombele following a breakthrough in discussions.

Son‘s 14 appearances this season have yielded 11 goals and five assists, the remarkable stats in part-owed to his new interchangeable role with Kane.

When asked by Football Insider if a new deal for the winger should be the top priority at the club this year, McAvennie said: “It is massively important that they get him tied down.

“Son and Kane have a great understanding at the moment. Who would have thought that Harry Kane would be coming this deep?

“Jose Mourinho has taken so much pressure off him. He is loving it and he is no longer making these lung-busting sprints in behind, Son is doing that for him. They have the best of both worlds.

“They are doing so well. You have got Gareth Bale to come into that as well. What a wonderful front three that is.”
