The problem in a nutshell, but unless there's an alternative solution (back up striker) which the management can then be seen to either use or ignore then Harry remains the only option, fully fit or not.
But will that alternative (back up striker) ever be wonderful enough to tempt a manager to seriously consider them an alternative to Kane given the choice on any day that matters?
I think it's a conundrum that not just we struggle with, most top sides don't have this well covered. Who's back up for Lewandowski ? ManC don't have an out and out 9 back up, they have Jesus who was a wide player in Brazil and still can play more than as a 9. Until last season who was back up for Benzema ? The conundrum complicated by the prevalence for single striker systems (or even no striker systems) that most operate these days.
I'm not saying that I think we've handled this brilliantly, I think there were better solutions to this than we have found. I really really did not understand the Bergwijn or Gedson transfers when we could have used those funds and non HG births to actually solve more important issues.
Bergwijn is a wide player who can play as a striker (or did in holland anyway) but I think in the summer we could have prioritised a 9 who can play wide instead - someone like Leao, Rebic, Niang. Others have suggested other players.
But none of them would likely resolve that eternal conundrum of having a like for like back up that would replicate what Kane does (when he's fit and at it), or a back up of such good quality that we don't all slaughter the fucker (a la Janssen) as soon as he gets a run out. Leao can't get a game at Milan because 50yo Ibra gets picked ahead of him.
I would have lived with any of the above as a solutions, I didn't hate it when Janssen got a game, didn't think he was anywhere near as terrible as others did,
for a back up, but I'm pretty sure a lot of those banging the back up striker drum relentlessly will be banging the "not this cunt" drum as soon as we sign some back up and he plays and doesn't score a Hatrick every week.
