For me the blame for our situation lies in 3 areas:
Lai for reasons already stated
Jones who is trying to fit square objects in round holes. Belgium had world class defenders who are comfortable on the ball, We don't.
Belgium have world class midfielders who are both creative and full of running. We don't.

Moore. Yes he's been hung out to dry. However as Head coach he decides the system that we're going to play. To a man of his football experience, it should have been obvious weeks ago that 3 at the back won't work and he should have adjusted things. Instead he does the same thing week in week out and plays the same players in positions and roles they are not cut out for.
