What a difference 10 Premier League games make.
After the first a disappointing 3-1 home loss at the hands of Aston Villa there were resounding shouts of "Wenger out" and so forth, now there is a lot less of that. The only sound you currently hear surrounding the Emirates is a definite reverberation of optimism.
Arsenal currently sit top of the Premier League table by five points, although it is early days. Nothing is won in November but the signs are very good indeed. The signing of Ozil has been instrumental not just because he is a world class midfielder, as he has proved with Real Madrid and the German national team, not to mention a handful of Arsenal games already since his deadline day move, but he has been a catalyst for change.
The atmosphere that surrounds the stadium on match days is now one of expectation and not resignation, something that has been amiss for a very long time.
Arsenal are starting to turn a few heads and prove the doubters wrong, after very routine wins against sides such as Norwich, Fulham and Stoke.
It was being thrown at Arsenal that they had not been tested, but with back to back wins against Liverpool and away to Dortmund maybe it is time people took note and seriously considered Wenger's men as contenders.
Yes the squad depth is a concern, but if they can stay top until Christmas this is something that is certain to be addressed in the transfer window.
There has already been positive signs that Wenger will buy in January. It is no secret that his main priority is a second striker to take the load off of Olivier Giroud, Arsenal had a £20million bid rejected from Juventus this week for Fernando Llorente which shows a sign of intent from the club to keep spending, whilst all the while they retain a keen interest in Atletico Madrid's Diego Costa
One BBC pundit, Alan Hansen, had just a couple of weeks ago written off Arsenal as contenders due to their weak defence. This the same defence that went to the Champions League and Bundesliga runners up, kept a clean sheet and became the first English team ever to win in Dortmund.
That result was very reminiscent of Arsenal's visit to Munich last season that rejuvenated the squad to finish in the Champions league places yet again... not bad for a club in 'crisis'.
Arsenal, who notoriously flounder in November are flourishing at the moment, the confidence is high and they would be a side you would want to avoid at the moment, they are on a good run and have more points (25) than they have had at this stage in their previous Premier League title triumphs.
Manchester United appear to be overwhelming favourites for tomorrow's clash in spite of Arsenal's good form, and although Arsenal have not won at Old Trafford since 2006 this will be a very tight game.
It's certain to be the perfect barometer to see how far Arsenal have improved but also how far Manchester United have fallen under new manager David Moyes.
