Lol we are gods If we get him for 70m max. It's probably bullshit though.
70M is a fair price. I don't think Ajax are being robbed, or that we are lucky.
He is still somewhat unproven, he do makes mistakes and he has got his fair share of flaws.
He is definitely capable of becoming one of the best,but he is not there yet.
70M is a fair price imo, considering the fact that defenders usually cost low and he is still just 5M shy of most expensive defender. And I'm sure there will be performance based bonuses as well.
