I'm sure everything will be reset now for the start of next season. There's no point in flying planes, booing, bringing banners etc. He's here for 2 more years at least, they obviously won't sack him no matter how hostile it gets.
The team will always have my support but I'm appalled with the people in charge of this club. Not going to spend another penny on them for a long time.
All I can say for Wenger is that he better hope and pray he can turn it around over the next 2 years, because this season will seem very pleasant in comparison to what will inevitably come his way.
