Every average team has the blueprint to beat us. It starts by knowing that if they have a shot on target then it has a good chance of going in and then (until recently) it was just a case of staying in the game and keeping enough energy in the team for the last 10 minutes to “have a go”.
I warned at the time that Ten Hag had been resting his key players for the final (because Euro qualification was unlikely any other way, at best Conference via league position) so yes, they did work out how to beat us. Maybe not so much tactically but definitely strategically.
