Don't understand where people think Kane can go with his game?
We know Lukaku is going to improve his first touch, his work rate, his positioning, his hold up play, his overall consistency, probably quite easily and quickly potentially to the point of being the world's best striker as there'll end up simply being nothing he isn't phenomenal at.
Kane may be the overall better player currently but doesn't have that natural slippery close control or pace of Lukaku, nor glaring weaknesses in his game that can be improved on and rapidly. Where is he going to be in 5 years' time in relation?
M'Bappe and Rashford have the same sort of relationship in that Rashford has a lot he can improve on while M'Bappe already looks quite complete as it is, although when Rashford does round his game up he'll only be as good as M'Bappe.
With all due respect, I don't really understand this argument.
Firstly, Lukaku is 24. There might be some improvements in his first touch but at this age, pretty much what you see is what you're going to get wrt first touch. I think he's past the age where he's going to be making major improvements on that (not as a player in general but specifically on first touch).
This is also a very similar line of reasoning to Bale vs Nani, that was had here quite often. The argument being that Bale was a speed merchant with a powerful shot and had reached his peak, with little else to improve on, whereas Nani had a long list of attributes he could (and would) improve on. That isn't how it works. Just because a player has glaring weaknesses in his game, it doesn't mean that they're going to be resolved. Similarly, a player with no glaring weaknesses can still greatly improve.
3 seasons ago, would you have imagined the improvement that Kane has made? And yet, would you have said that Kane had glaring weakness then either?
Kane is continuing to improve. That despite having no glaring weaknesses.
Mbappe I think looks like an absolutely insane talent but that doesn't take away from how accomplished Rashford is. Easy to forget how young Rashford is with how he plays.
