In my opinion, I think one of the problems has been confidence. When you're on an international break or what not, and come back, pre season involving a lot of rotation etc, it seems as if we've almost forgotten what we were so good at.
Problem is, as soon as we let in one goal through zonal marking, the confidence drains, the fans can see it, the players can see it, and everytime the opposition gets a corner, they're almost bricking it. We can be grateful our next game's at home to Burnley, who no disrespect to, aren't a very good side in the air. They seem to play most of their football on the deck, and I'm fairly certain we won't concede from a set piece, let alone at all for that matter, unless some massive fuck up/wondergoal does us.
Pisstake how easily City are scoring from set pieces mind you. Take Villas goal as well yesterday.
