After ending nine empty years with the FA Cup in May, they truly enjoyed this victory, back at Wembley Stadium, gathering more silverware and a slice of revenge on a team who keep poaching their players and smashed six past them at the Etihad last year.
More than that, offering further evidence that Arsene Wenger may have his team moving in the right direction at last. Keeping players, adding new ones, shaping them into a unit with balance and solidity as well as flair.
It is ever thus, in this fixture. If it goes badly, as it did for Manchester City, then shrug and pretend it’s nothing more than a glorified preparation game. If it goes well, seize the positive aspects and squeeze all you can from them.
