I'm going to take this as you are not trolling, but if you don't want to get banned, my tips are for you not spamming on walls.
Okay, why do people want Wenger out after his work? My answer to this is that he simply isn't the right man to lead us to glory anymore. That's why. Of course, his time can't be forgotten, and I do see why people want him to stay after the whole money issues we had, but since, it's not like we had a new revolution. A team of Arsenal's caliber shouldn't be winning 2 trophies in 11 years. It's simply not good enough. Yes, he consistently got us top 4, but repeating cycles year after year can certainly get tedious.
If you ask a WOB why they want Wenger to currently stay, 99% of the time they will talk of the past. I also disagree when you say
Wenger is the one who made the history for the club. Without him, Arsenal is nothing.
Graham won 2 trophies in 8 years, Wenger 3 in 20. I know what I'm choosing. Wenger in my opinion would be considered the best manager if SAF wasn't around. He was a shade behind SAF. SAF won 13 titles himself if I correct. That shows how great of a manager he really is, even when it took him 2 years to win an FA cup like LVG.
This probably isn't the best way to put things, but I hope you see why people want Wenger out.
PS: I thought you were a Madrid fan. It's really odd seeing you with a photo of Wenger.
To all Arsenal fans and others, Wenger is the one who made the history for the club. Without him, Arsenal is nothing. Look at Man U without Fergi. Even Mou is struggling.
I need someone to state why you think that he is a bad manager. He continues to add more great players for the team.
P.S. I'm not trolling.
