I want Wenger gone more than anything but I am certain that even if Arsenal do not win the EL he will still be the manager next season anyway.
This means that Arsenal might as well win the EL and be back in the CL next season.
Wenger is guaranteed to fuck that up as well as the whole season which will hopefully mean there will not be another contract for him in 12 months time although that is far from certain.
Arsenal are a pathetic club who don't want to win, they are just happy plodding along whilst making money and that will not change until Wenger and Kroenke both leave.
