Claudius I think you're taking away too much from ten Hag here. I give him a lot of credit for motivating his players to commit in every minute regardless of their contract situation, age and pay packets, for not having to rely on a major defensive error for his side to get a shot on target, nor a teenage prodigy to keep in things, and to have led the organisation of a stoic defence, the plethora of gilt-edged chances given up by which definitely reflected a cruel injustice rather than the kind of season long pattern that would call a lesser coach's entire system and indeed, capacity to communicate into question.
But not with Erik ten Hag: with him, you're guaranteed of a fighting chance of every victory.
