It's a smart, safe appointment with an unknown upside (his team's set pieces are very good, so not worried there). Watkins, Raya, Toney, Mbeumo, Wissa, Damsgaard, lots of player development there.
Not worried about the 6 (we need one, just not the WC/Elite one that would be need for any chance of Ange's system working), he will pay two in front of a disciplined back 4.
I think people will be really surprised at what decent coaching, system adapted to player strengths, and not leaving yourself exposed every game can do. I don't see us ever finishing below 7th with this guy. The real questions is the additional games (he did have two seasons in Championship, more games there) and sub use, Brentford would not have had the bench we do/can have.
