Nah, I don’t think you see the full picture, around 35-40m got to be the max, and I doubt the club would go much higher.
First of all, I don’t think Lewa or Benzema are good comparisons. Much easier rides in Bundesliga/La Liga. Meanwhile, Zlatan always took a lot punishment and carried a heavy duty for his team — and he lasted to what 40 before he started to tackle off. So you never know.
So why did I use Higuain as an example? For the simple reason that I don’t think anyone know for certain how much Harry Kane has left in the tank. I am definitely not guaranteeing that he will tackle off in the coming two years like Higuain did. Nor would I at all be surprised if he did. I mean, Harry Kane is big body and he plays a physical style.
If we sign Kane for “just” 60m, give him 350k per year, and give him a 3+1 contract — the yearly cost is what 30% more than CFC is paying for Enzo. In that case, you just must be certain that you get more than 1-2 seasons from the player.
If we pay 30m for Kane, the yearly cost becomes 27.5m per which a little more than what Antony cost us per year. Maybe you can go up a bit to 35m. 40m? But that got the be the limit unless you have a med team that can come in and guarantee that Kane has 5 year left in the tank.
