I think it's a bit simplistic to say "City are better, as proven..."
For me, I think what is pretty clear is that we have a manager who is the best in the business at managing a team over the course of 38 games. The best at rotating the squad, keeping everyone happy, dealing with injuries and suspensions. We play at a high level, week in, week out, with a high level of consistency irrespective of who is available. Therefore more often than not, we come out on top, over the course of a season.
If that defines "best", then fair enough, we are the best.
But does that mean we are the best in a one-off game, or over a shorter run? I would say we are not. There are countless examples of us fucking it up in one-off games where we should have won or gone through, but tooled it in.
When Liverpool won the league, they were blessed with being able to play their "A" team, virtually every week. They were extremely fortunate with lack of injuries, and that is very unlikely over 38 games, which is why they have only won it once.
But I think it's entirely possible they can do the same over their remaining 13 games. If there were 30+ games left, I would be very, very relaxed. With only a third of the games left, I think it is squeaky bum time.
