You want to judge us on a game from 2011 and then accuse me of basing it on one game. I like your style.
We've conceded more goals than at the same stage last season and we're further away from 4th than we were then. It's only Man U's complete and utter collapse that is stopping us being 6th.
I mentioned two games; but I could have chosen many more. The point was that we have been competitive in every game this year bar the first one while under Wenger during the last 3-4 years of his tenure it seemed like we were absolutely hammered by someone every year, often several times.
But that is a side issue. We are currently on pace to finish 13 points ahead of last season so it is fair to say that Unai has had a very good start especially when you consider the 22 games undefeated. But ultimately, as you say, he will be judged at the end of the season.
In the meantime, it is perfectly reasonable for an Arsenal supporter to comment on the good start we've had. I don't really understand how an Arsenal supporter could disagree and try and find fault with the team or the manager.
