A hard game to get accustomed to quickly. I really don't like to see changes made to the back four unless it is due to injury, or perhaps if someone is on the cusp of getting sent off. It really does cause a lot of disorganisation and it showed. Surely McNair could have slotted in at left back and just kept things neat and tidy. Ending the game with only 1 out of the back 4 still in the position they started in seems excessive.
A little poor from him for the goal, but it was a strange time to bring on a defender, so I'll give him the benefit of the doubt a little. He looks very talented, especially on the ball. I'd like to see more of him if Blind is going to play at left back, which I would be fine with. I do like Rojo but I think Blind has more about him at both CB and LB.
Smalling and McNair could be a good pair. McNair is seriously composed for a lad of his age and experience.
