A decent victory, not vintage by any means but positives are Cazorla getting a double which should hopefully help him find some form and another clean sheet for the defence.
If we are to have any sort of chance we have to be hoping that Chelsea and yourselves drop points over the next few weeks for us to create a gap. Utd to get something today, Spurs to get a point against City and a draw in the City vs Chelsea game for example would give Arsenal a little cushion going into the initial double header (of course we need to beat Southampton and Palace and these are by no means a given).
However, if results go Cheslea and Citys way in these games, I'd imagine that we could be overtaken around the double header mark and we would really struggle to catch back up.
I'm not overlooking the Southampton game or trying to predict results up ahead, just trying to paint a picture of the only scenario I think would be needed to give Arsenal a fighting chance at this league.
