Well...that's the end of the title race then.
Unfortunately, yes, I think - barring some entirely unforseen and unexpected disaster befalling Manchester City - I think that it is.
I sincerely hope that Arsenal don't collapse for the remainder of the season.
And - while it was gracious - Manchester City commenting about how tough the game was (no, we were oufought, outgunned, outclassed - if it had't been for Ramsdale, who was excellent, we could have been defeated by 6-1, or 7-1, for, apart from a few sporadic scatter-gun attacks, we never really threatened them) does rather stick in the craw.
Worse, I suspect that this is a dress rehearsal for what will happen when we see the crowning ceremony for the actual title, when Manchester City will congratulate Arsenal with platitudes about what a powerful challenge they offered, what an excellent team they are (and difficult to defeat) and how Mikel Arteta has shown himself to be a worthy and diligent disciple of Pep Guardiola, but hasn't yet managed to surpass the master.
Yes, manners matter, - of course they do - but, for Manchester City, I think that this is all a little too smooth, a little too glib, and a little too easy.
