There is no difference in coaching.Could be! This is also a good demonstration that for all your complaining Southgate was far from a poor manager in the previous tournament. This is what a poorly managed team looks like
What's different is that we had Maguire at the back who's incredibly underrated - along with Shaw - and an in form attacker in Sterling who could hold the ball under pressure, dribble, had good positional sense in terms of knowing when to run in behind for Kane, etc.
Southgate has never been a good coach or tactician. Our previous teams were just sit back and hope Kane and Sterling do something.
