We really did Chelsea dirty this window damn.
Part of it comes down to the inexperience of Todd Boehly in football.
He is a good businessman, and he respects his negotiators (unlike others) doesn't lowball them, but he doesn't have the expertise to be an SD.
If they had an SD, they would have avoided the embarrassment of Raphinia and Kounde deals, they wouldn't have gone into negotiations to begin with.
Edu, Arsenal's SD, explained it well about Raphinia. He said he had talks with Deco where he understood the player has set his mind to go to Barca, hence they didn't started negotiations with Leeds, even though he was their target 1 for the winger position.
