Few things I noticed in the 1st half:
1.) Blackett takes way too long on the ball, gives the opposition sufficient time to cover short passing options and start closing him down
2.) Fletcher has a terrible first touch, and that is his main problem at the moment as it allows him to be closed down as he either tries to get the ball out of his feet or knocks it too far ahead of his reach.
3.) Rooney's passing was woeful today, one of the main reasons we struggled was how dismal his passing was.
4.) Herrera's positioning was terrible too, he kept charging ahead expecting the defenders to bring the ball out of defense.
The defenders clearly lack the confidence to bring the ball out from the back, and that's causing most of the problem when we play 3 at the back, as we need to start the attacks from the back, instead of punting it forward hoping for a lucky break
