Most people noticed the yawning gap between midfield and attack as Manchester United were picked apart by Manchester City in the first half of Sunday’s derby.
The hosts were allowed to show the peak of their talents as a result and United found themselves 4-0 down at the break. On the surface, it looked as though Erik ten Hag had got his tactics wrong.
