Paul Stewart has warned Tottenham Hotspur would need to spend £300million to make their squad competitive if Harry Kane departs this summer.

Star striker Kane, who picked up the Premier League's Golden Boot award and registered the most assists last term, has made it clear he wants to leave Spurs in a bid to win more silverware.

Manchester City have the England captain marked as one of their top transfer targets, along with Aston Villa talisman Jack Grealish.

The Sun originally reported Kane is poised to join Pep Guardiola’s City for £160million after Spurs chairman Daniel Levy agreed to allow the England skipper to depart last week, but the Premier League champions hit back at the report and dismissed it as nonsense.

So far, Spurs have welcomed Atalanta goalkeeper Pierluigi Gollini on a season-long loan with an option to buy while Bryan Gil has joined from Sevilla with Erik Lamela going the other way.

But Stewart believes chairman Daniel Levy would need to allow new head coach Nuno Espirito Santo to spend big if Kane gets his wish and moves to the Etihad Stadium.

Speaking exclusively to Football FanCast, the former Spurs man said: "If they get £160million for Kane, they've got to spend £300million at least to get a team that's going to compete, but that's not Daniel Levy's style."
