Wenger has had his chance now, there's too much wrong about his methods and he's not the man for us going forward. Tactically he's inept, he's been found out time and time again when we've had key games at key times, the injuries are just ridiculous and have been for as long as I remember and still nothing seems to be done about it (it's like we're in denial and just thinK it's bad luck), his transfer policy is heavily flawed, time and time again he just won't do the necessary to make us genuine challengers for the title.
On top of that there's the awful football we play, yes 1% of the time when it comes off it can be good but the rest of the time it's dull and repetitive, as far as our form is concerned we never seem to play like a team on top form, more often than not we're scraping wins rather than winning games at a canter with great performances.
I don't seem him winning anything major and don't see him taking us to the next level, he refues to adapt and change and his methodology is now outdated, yes he won the FA cup which is great but at the end of the day winning that competition isn't the hardest as you can easily get favourable draws and avoid the best teams. He's had 20 years to succeed in the CL and all he's managed in that time is one final, this is despite having one of the best teams in history at one stage, nowadays we jsut seem to make up the numbers every season.
So let's just thank him for what he's done shall we and then move him on so we can finally look forward to something different, probably more exciting and more unpredictable, perhaps a new era where we can finally realise the potential of the club and not just settle for being 3rd/4th place runners up every season, which if not for the CL cash cow which shouldn't ever exist IMO (not for teams other than the winners, or the winners and runners up at the very most) would be meaningless after the 1st 1-2 times of reaching that position.
