I guess you have to look at the previous sales trends. Just before Covid, the prices of players were rising at an alarming rate and there was so no stopping them.
Also, a lot of players were being valued at ridiculous prices in last 2 to 3 years. I mean if Higuaine costed more than 90, anything would be possible. Hell, Fred costed 52 million and Mcguire costed 80. Ousmane Dembele was 105, which Dortmund sold during that golden era of selling players at high prices.
But suddenly after Covid things started to change. Clubs who were big but didn't have sugar daddies -- which had Romans or Shiekhs as their first names -- were badly hit. In fact, to my knowledge, clubs like Barcas and Madrids and Juves (who already were walking a tight rope) were hit alot.
The financial situation of a lot of clubs has gotten worse and it certainly seems to me that it will keep getting worse until fans are allowed back in. It was very stupid and daft of Dortmund to be so stubborn about asking that high sale price of Sancho. Also, now they know what is the price of keeping an unsatisfied player in your squad.
And as far as Sancho is concerned, I really do think that he will massively improve our squad. But so would Dembele or Adama Treore because we haven't got a player of that skill set in our squad. But Sancho is no where near a finished article as some of us believed. He needs time and maturity to reach to that level and he sure will with time and hard work because he is talented. But until then asking that kind of money would be living in 2017.
