Great play from Arsenal, our defence just being rolled over. Amartey at fault for their second IMO. It was great play to get in behind but anyone with half a braincell would have sensed the danger and got to the ball first to make the clearance. Amartey just doesn't have those levels of concentration and intelligence at reading the game.
I can see why Puel doesn't want to play Ricardo at RB, he's lightweight defensively but when the best alternative you've got is Amartey you're asking for trouble.
Also an interesting facet is the way Puel has Vardy back defending, not having him hanging around midfield as we are more accustomed to seeing, he's always back on the edge of the box when we're out of possession now.
