Although the focus will be on the Tuchel for his subs and overall game management, the players we have show the lack of quality in technical ability and nous.
England had 12% possession after the goal, retreating deeper and deeper, which started before the defensive subs. not even counter attacking teams allow that amount of control from the opposition.
The way to defend against a team as skilful as Argentina is to contest the game. England, as has been their sempiternal failing, simply don’t have enough quality players to hold on to the ball to start any counters or even seem to try to keep the ball for a moment.
Moreover, compared to England, Argentina are better even at longball, every Argentinian cross seemed to find an Argentinian head, despite the fact that their players are nearly all far shorter than England's, Lautaro Martinez, who scored the winner is 5'8", and every England cross or longball hoof found an Argentinian head.
