Three very poor goals to concede from a defensive point of view, though all three were very good finishes.
First - There is absolutely no way that seconds after going ahead, and from the kick-off, that your fullback should be left 1 on 1. I also don't think Stevens will be happy letting a shot across him in from that distance.
Second - Cross comes in too easily, poor headed clearance from McNally, Fossey is stood in acres of space, assume he is Sykes' man because if you pause it as the cross is hit, Seddon is in the defensive line as you would expect for where the ball is coming from. Fossey is beyond Sykes.
Third - Narrow defensive line, allows for the ball to go down our left hand side, where the space always is (every game), Seddon is picking up their number 17, Sykes gets caught between tracking Fossey or coming towards the man with the ball, and McGuane doesn't press the passer of the ball fast enough. If you pause it at the beginning of the move, our defensive line actually looks okay with an arc of 5, but the 4 players in the middle of the pitch are in a clump - Kane & McGuane practically next to each other on the halfway line - and Bolton spot this and get the ball wide.
It's a great pass for Fossey to run onto, good cross, and good finish. But of no surprise at all, that it came from a ball into the space behind our left sided players.
