if you want proven players and not talents. yes, 90 mill is the current price tag. Same for Kai Havertz, he is having a 80 mill € price tag.
Even Corona wont reduce the prices significantly i guess. at least not for long term contracts like those two currently have.
I don't really care about his price tag. I have no idea how much money we have to spend, market prices or anything like that. I care about bringing in the right players. The valuation of those players is up to the people involved in negotiating the transfers.
I'm all for us buying young talents, but not instead of world class players. The talents should be bought in addition to world class players. Also, the talents we buy should all be in the "world class" category, as Rodrygo and Vinicius in Real Madrid. Luckily, Sancho is both a world class talent and a proven player already.
When we have a squad good enough to challenge for trophies in every tournament, we should focus on maintaining that with young, potentially world class players, with the odd "ready" player bought every now and then. Until then, we need at least two (possibly three) first XI players, who all should be in the world class category.
