Great, well thought out post as usual, you're spot on with the player we have signed we should be better not on a par with previous years.It's very simple. We are perennial top four finishers. 2 of the the teams we have tended to finish behind have had either poor (Manure) or shockingly poor (Chavs) seasons by their standards. They have both suffered a lot of disruption on either the managerial or the playing side. The other team - Citeh - have been astonishingly inconsistent by their standards, and it is clear that they too have been disrupted by speculation about a managerial change. Of the other 'traditional' also rans - we have Liverpool who are in transition, and have not featured as a threat; Everton - who have been disappointing; and Spurs - a team that in terms of stability are nearest to us.
By contrast - we enjoy the greatest stability of any team in the EPL, and Wenger has enjoyed the luxury of a lot of time - years in most cases - to work with his players and his system.
Next - the quality of players at our disposal. We are fond of bleating about those clubs with greater resources than our own, but Citeh aside those clubs have been taken pretty much out of the picture this season. And we have considerably greater resources; have a bigger and better squad, and a higher wage bill than most of the rest of the league. Our players are technically better than most other teams, and on paper we should beat most of them. Of course this is football, and there will be surprise results - but it is facetious to argue that over a period of time a stronger team, and squad should not prevail.
Then let's look at the players we have brought in - at huge cost in a couple of cases. We were top four finishers before Ozil and Sanchez joined Arsenal. They are both world class players - yet there has been no demonstrable change in terms of overall points won since they arrived and bedded in. To them we added Cech - the world class keeper who has already been worth quite a few points this season on his own. You would have thought that with 3 genuine world class players of the type we have not had for many seasons we would be stronger as a team - not be sinking to the mediocrity of the rest.
I do not expect to win every game. But given the factors above, I would have fully expected us to improve on our level this season - rather than to follow the rest. I do not understand your suggestion that because everyone else is mediocre, we will inevitably be mediocre too. It just doesn't make sense. And what's more - if that is really the case then we are about as far away from winners as its possible to be.
I think it is obvious that this season above all others is our best opportunity to win the league. And we should be winning it by some distance if we look at the number of average performances and needlessly dropped points we have seen from Arsenal.
I have never suggested that if we do win the league it will somehow be worth less. I don't subscribe to that view - as a title is a title and nothing more needs to be said. But we are doing our best to squander a golden opportunity to do so.
