Perhaps, but Levy would thus prove himself to be a fool.
With or without Kane, Spurs are not joining the top four club in 2024. 5th is probably unrealistic, but let's call it borderline realistic. Daniel can believe otherwise, but when he finds out that Harry could not possibly deliver a top four spot and then watched him walk away on a free he will watch his club go into freefall. City, Arsenal, Liverpool and United are no longer competition for Spurs, who really have to be more worried about Newcastle, Brighton and Villa -- clubs that are in no way flukes to have finished Spurs last season.
Daniel can do a lot with 100m to rebuild the squad to enable it compete with the top four clubs, but he can do very little with the meager budget that he'll have after Harry leaves on a free and, if this what he decides is best for the club then he'll be treading water with the likes of Villa who look prepared to put Spurs in the rear view mirror.
If by the end of August Harry has refused to sign the new contract and Daniel decides to mortgage the future of Spurs for one last season for ol' times sake...club supporters will not be amused. The playbook Daniel should be looking at is from Liverpool when they sold Coutinho. It changed everything for Liverpool.
