If you can't see the quality that Brereton brings and the improvements he is showing, I would absolutely question your knowledge of football. Not question Tony Mowbray who has spent his entire life in football.
You didn't spend your life in football. You will have spent a life of talking about how football should work.
I have spent decades surrounded by numerous people who have been going to football matches for 30/40 years, but have absolutely no understanding of the actual game, and how it works.

Its all good and well sitting online saying all this, making no decisions, seeing no training, never playing a game of professional football in your entire life. Being able to work with young professional athletes, whilst also understanding how the inside of a football club works, how to stabilise a sinking ship. How to do all these things at once is a skill set you, me or anyone else not involved in football would understand.

Which is why this stuff is ignored, and your comments are just that. They mean nothing, have no impact and carry no significance.
