Not really, I mean defenders even at the best do not go over 100 million as far as I know (maybe I am wrong) yet I have seen so many players sold over 100 million because they are offensive players, and even better yet now there are even more in the talks, Kane and Haaland are in talks to be over 100+ very easily as well. I am not saying defenders are cheap, all I am saying is it is easier to get a good price for a good offensive player whereas it is not that easy to get that money for a defender.
The greatest defender in the world right now versus not so great offensive player worths around the same. Like VVD is the best defender in my mind (not saying he is, just according to me, you may think someone else) and he worths as much as Sancho and Sancho worths half of what Haaland worths. See the difference? That is why defenders do not really worth the same.
Attacking players always have higher price than defensive players. Always. The transfer market need many more years to see a goal keeper or a defender who has transfer cost more than $100 M. There will be defensive players have that cost but not now, not in near future.
The pandemic brings crisis to many clubs and affect their balance sheets and it will prevent the inflationary price of soccer players. With the general downside on the market, defensive players will not have chance to hit $100 M.
The only hope for you is the fiat inflation keeps exploding more and more.
You're right, aside from the problem I think Pique is getting old, it's about time they looked for a replacement alternative. After all, age will eat up his physical strength, experience will not be enough to withstand the opponent's fast attacks and fast runners. I've read that they are interested in Alessio Romagnoli from Milan, Lisandro Martinez from Ajax. But do they still have enough money to line Pique? They are said to be having a hard time with money.
AC Milan won't let Romagnoli go too easily because he is the captain and a leader of their defense system. AC Milan need Romagnoli to have stability for their defense system that is basement to fight for titles.
