The transfer window hasn't even opened. There have been no hints we are in for either player nor that we aren't looking at both. It is ok to have a preference towards one or the other, and also to point out when people go way over the top in exaggerating one over the other.
Of course Haaland might not want to move, or even if he did, might not be affordable in what the club are prepared to pay. Same can be said for Kane, although he has at least hinted he wants to move (which people have taken to be a done deal, to us).
But saying he guarantees 40 goals a season and league titles next 5 years is crap. For either player really, but the claim then extends to say the other wouldn't cut it. So if my pointing that out does your head in, apologies, but I stand by my point.
