Playing devil's advocate, I'd point out certain clubs and managers have made a life for themselves doing just that repeatedly!
This is a rather harsh and one sided way of presenting that game.
Our 2-3 chances were the only decent chances of the entire game, because our defence was good enough to restrict Villa to shooting wide from 25 yards + all game. As you said yourself that day, it was the best organised we'd ever looked in the PL.
If you can monopolise the decent chances in any match, you're probably going to win.
Obviously we're not going to keep Man City, Arsenal (or Liverpool) away from goal all game no matter how well organised. So there is fair argument for wanting to carry more threat and accept we will give chances up at the other end inevitably.
Against City, two of the goals came about directly because we went on the attack, and got counter-attacked. We could have camped in our half and refused those openings to go forwards, and probably kept the score down to maybe 2 or 3, but we do have to find a balance.
I think most would agree our second half balance on Saturday was better. But let's not throw the baby out with the bathwater and denigrate what we have done well so far this season for the sake of fitting a narrative.
