The first 45 minutes was the epitome of two teams cancelling each other out – but once the second half began the landscape was set for City’s win.
They were the more progressive, aggressive side. Their attacking intent started to overwhelm Arsenal, the pressure became impossible to resist. Smoother on the ball and more cohesive than an Arsenal side based on organisation, the traffic only flowed one way.
Arrizabalaga already had Arsenal’s nerves on edge with an injudicious dash from goal which resulted in a yellow card for a panicked foul on Jeremy Doku.
Much, much worse was to come for Arsenal and their goalkeeper.
It remains six years since Arteta won his one and only trophy as Arsenal manager, and the way in which his team went into their shell here will be a concern that he must hope is not repeated as the pressure mounts in the closing weeks of the season.
Former Manchester City goalkeeper Joe Hart told BBC Sport: “Manchester City played to win. I think that’s what they’re bred to do over ten, 15 years. I think now they’re very much bred to win. I think they’ve been really disappointed with the FA Cup final at the end of last season [when they lost to Crystal Palace].
“A lot will be read into it putting a marker down or whatever, but I don’t think so. I think it was just about Manchester City winning trophies, which is what they’ve done so regularly recently – and this is another big one.
“It is also a huge day for Pep Guardiola, who’s won everything, but now stands alone in terms of managers winning the League Cup. He’s won it five times, going one clear of Sir Alex Ferguson. How much of a testament is that to his ability, his special touch and what he’s done over the years with Manchester City?”
Arteta is braced for the battle to recover from this setback and focus on three trophies, saying: “We had eight amazing months with this team. Today is a disappointment. We need to use that fire in the belly for the next two months to have an incredible season.”
He told BBC Radio 5 Live: “It’s painful, especially for our players and supporters, because we really wanted to lift that trophy. It was two very different halves, especially the first half when I think we were better than them and had the best two chances of the game.
“We didn’t capitalise on that. Credit to them for what they have done. A really sad day.”
He must hope it is the last sad day of what has been an outstanding season so far – for Guardiola, he will hope City’s win, and the manner in which it was achieved, will play on Arsenal’s nerves.
