Whilst accepting that the introduction of a defensive (unnamed in this post because it wasn't his fault....but we know he'll get the blame) sub on 72 mins was the key event, it had gone downhill from the moment they scored.
From ESPN
From the 55th minute when Gordon scored through to Argentina's winner in the 92nd minute, England had just 12% possession.
They allowed Argentina 37 minutes with 88% possession -- a team who at that point had four forwards on the pitch, stretching England's defense
and offering midfielders Alexis Mac Allister and Fernández time on the edge of the box.
However, the problem did become more noticeable after 72

Morgs only touched the ball once between the formation change and the winner. James and Spence touched the ball just once in the Argentina half between them after the 72nd minute
James (and his replacement's) average position after 72, was behind Pickford
