For as long as he cannot go to a Champions League club. You cannot honestly believe that a player could decide to stay at a mid-table club for his career and give up on Champions League football (which he's never going to get at Spurs) if big clubs come approaching, it almost never happens. Question is whether Kane is going to become that good that he attracts serious interest from clubs like United, Chelsea, Real Madrid, Barcelona, Bayern etc.Bad news for those who hoped that United had chance of signing Kane, since he's just said (in an appearance on BT Sport’s Clare Balding Show): "Spurs is where I’m at and where I plan to be for a very long time."
