If blame is to be assigned for that one it should be laid at the door of Armstrong who decided to pass the ball out of defence (seemingly trying to start a counter attack), when he should have punted it as far down the pitch as was possible, ideally for a throw in by the england corner flag.
Then there is the unforgiveable marking as Armstrong, Brown & Tierney stood and watched the cross coming in, Leaving Berra, Mulgrew and Tierney to mark 5 England players however all 3 of them also decided to watch the ball. Had Kane missed it, Smalling was right behind him for a tap in.
