I cannot criticise GS too much, he seems a genuine nice bloke and has certainly improved Englands performances. But . . . !
What was so noticeable to me against, especially Italy, but not only Italy, was the lack of ability to keep possession and progress up field. Italy, after the first 20 mins were keeping possession, quick accurate passing between players in triangles, players always moving, in front of the ball giving 'options' England seem largely incapable of this ? Their 'retain possession' routine largely revolves around passing it square across the last defenders. Shaw turns back inside, passes to Macguire, on to Stones, on to Walker, etc etc, ringing the changes by alternately passing back to Pickford who promptly 'launchs' it and gives possession back to Italy. There is a noticeable lack of movement ahead of these defenders, hence the square passing. When we do try to 'shuttle' the ball forward we rarely get far due to poor choices. I think this is in large part due to GS's preoccupation with defence and a desire to 'keep ball' sadly we don't have the necessary skills.
