The worst of the refereeing wasn't the possible red or the less likely penalties, but the spate of soft free kicks a little before their missed penalty, which seemed to take the sting out of our press. Those changed the flow of the game. We were a little fortunate that Henderson didn't get booked for stopping a counter and Fab for totting up.
Villa's high line is giving us opportunities, we're not executing them. Too many player pushed too high against their back line, not enough (vertical) movement, poor execution on some relatively straightforward forward passes.
