I don't think we "tried something different", I just thought the structure looked far better and more organized both in and out of possession. We simply don't have anyone that was ever going to cause concern for Arsenal at the back, and once they realized that and committed more men forward they played for corners and won.
But the structure actually looks sustainable and something to build off of, unlike the majority of Ten Hag's games where it looked like we'd just win or lose on a coin flip and there weren't any obvious signs of sustainability in how we might get consistent perforamances. We'd press high, create a key turnover or two, spoon a chance, and then tire out and leave a single midfielder to cover 60 yards of ground while teams cut through us. Then we'd get the ball back after a save, and look to immediately play another fast outlet ball to a winger staying high and wide and do it all over again. It was like watching a shite basketball game where we'd just accept we were either going to win or lose based off of chance.
