Harry Kane will cost over 100m and he is almost 30.
Haaland has a release clause of 75m and he is 20.
Spot the difference.
Well, let's say it like this - if you couldn't get Haaland for 75, would you still go for Kane for 100 mil?
Everybody will go for Haaland - that is the deal of the decade. A 20-year old world class striker whose all-around game fits all teams and tactics available at a knockdown price - he will have 10 top offers. Mbappe won't, he's in his own playground and only Real, PSG and maybe City can afford him.
Since Mbappe is destined for Madrid and Haaland will have so many options to choose from, I can understand clubs standing in line for Kane as well. If you need a striker and miss out on Haaland, Kane is your next best alternative - especially if you are an English club.
