I would like us to stick with Wenger for as long as possible, as long as he actually shows some ambition. I think we can all agree (well I hope so anyway) that an enthused Wenger is a sight to behold, and quite frankly he has looked tired of it all for the past 6 or so years.
However this Season is different, he seems to have rekindled his drive from times of old. Hopefully, this will drive (I was going to use the word "spur", but then I was sick in my mouth) him to achieve great things once again.
I think Klopp would be the only Manager that would be suitable as a replacement. He has shown on the highest level that he has what it takes...
I know Wenger was fairly unknown when we got him, but we were a mid table Club back then.
