Hoddle, Dixon and Wright on the commentary were moaning at Delph, Lallana, Berkely and Sterling for not doing their jobs and supporting Kane's defence from the front. They were saying English teams needs to learn to press to compete with the top teams, but that it's hard to drill a national team (Wright talked about the hours George Graham used to put in to perfecting it).
Dier and Alli replacing Delph and Lallana made us competitive/got us creating chances for the first time in the match, but did create space in front of our back 4 for Spain to exploit, because the rest weren't backfilling their holes.
