I'd say it was evens, Arsenal in general looked better than us, and Arteta has clearly improved them this year, but I do think a little bit of that also comes down to the same thing we benefited from.
1) Liverpool, Tottenham and Chelsea were all horrendously dog shit when anyone would have expected them to be so much better. I expect Liverpool to make something of a comeback next year.
2) Newcastle have looked immense and with another season under their belts they will only get better, this year was a year early for their project. They actually however have the benefit of a stable base, with signings this summer I can see them pushing that second spot out.
3) Arsenal had a pretty clear schedule all year long, and their lead came down to them not playing as many games.
I think we will see Arsenal drop to fifth again, they have a good side, with young exciting players, and of course we will likely see them buy some new players. However I think this may end up being a flash in the pan, I am not entirely convinced they can have that start to the season again, or that they will be more consistent next year when they are in the CL. This year was their chance to capitalise on some of the other teams having a poor year, them having fewer games to play, and some excellent team performances. I think we will see a City, Liverpool, United and Newcastle top four next year, and I still don't think we will win it.
