Those numbers are so off though... Atalanta is starting at a 70m EURO asking price, which is £60m. United probably will limit it at £50m which is a 10m drop. Probably a deal that would be bonus based to hit the upper end of the price anyway. Hojlund is on about £10k per week currently. There's not a chance he's going up to 175k
He's 20, it's easier to negotiating a lower starting point like 70k as his next contract will be the big one anyway when he's going to be more developed.
Kane would instantly demand to be the top wage earner (so 400k per week) and we wouldn't be able to get him for less than £120m. So that's more than twice what we'll likely spend on Hojlund, with Kanes being much less based on incentives than Hojlund being more of a future growth fee.
Yes, any fee comparison focusing on only 23/24 season and nothing else will be heavily in favor of Kane. He's literally 10 years older than Hojlund. The issue is that with Kane, his cliff could literally happen at any point. Past 30, you just don't know when a player will decline and when the decline comes, it happens rapidly. Hojlund just turned 20, we would be paying for what he can become while being confident we can handle the transition period.
Which brings me to an even more important aspect - what is our immediate target. 23/24. Realistically, are we title challengers? Nah. Not at all for me. There's a chance to fluke it like Arsenal tried to do, but we aren't there yet. We've got more developing to do as a team, there are a lot of changes on and off the pitch taking place that you just don't see a team that isn't fully settled who actually gets over the line. Kane doesn't get us over the line, while not getting Kane doesn't drop us out of a CL qualifying position. Our squad building should be looking at 24/25 as the start of the title push years. If Kane is available on a free, by all means get him. But if Hojlund hits and develops like the club would hope, then we'd be in a position to challenge repeatedly every year, rather than waiting for him to be 120m+ like Osimhen is.
If we were settled on and off the pitch more, have had a title challenge season under our belts, weren't about to have a big system change but just needed that final piece, then yeah, go and spend 100m on the top striker you are missing. We aren't there though.
