Maybe
You're wrong, no?
We've probably asked for too much and it was a risk for the buyer. Clubs are learning fast about the new type of overconfident arrogant youngsters and they will be less willing to invest in them unless they're crazy good on the pitch (which is not the case with Douzi).Our inability to rid ourselves of him this summer may be seen as a slight on us by some; maybe if we hadn't shunned him so firmly we would have had more luck.
That being said, this should be quite a lesson for Guendouzi as well. We put him up for sale and noone wanted him. That's gotta sting, hope that goes some way to humbling him.
I think people who are expecting that Douzi will learn a lesson from this underestimate the power of habit (in this case bad habit). It could be that he's building anger inside of himself instead of feeling guilty for his behavior. As I'm saying, clubs these days are better educated to scout for all aspects of a player, not just how he passes the ball around.
