I wonder why this place's so dead now

Come on guys, cheer up!
Just when we've given a pay rise to the manager and extended his contract for 2 more years, after a season where we failed to qualify for the CL after 20 years, to which our response in the transfer market was to take a £30m profit from our squad.
No biggie, is it?
I don't even know where to begin to go on about this clusterfuck going down at our club.
Wenger dismissed the idea of having a Director of Football working with him last season, implying that set up would have a few players forced upon him, players he didn't know or didn't want. So he wants to keep full control. So this is why we have the likes of Joel Campbell (6 loan spells) and Lucas Perez (barely used, now back on loan to Deportivo) and Mustafi (a £35m rated defender who they've just tried to shift on loan to Inter Milan after only 1 year). All of which are players he personaly chose, and wasted transfer and wages budget on.
About yesterday: after spending the whole summer saying Alexis wasn't for sale and would stay, they had accepted a deadline day bid of £60m for him... on the condition that Thomas Lemar would sign. So they put in a bid of 100m euros which Monaco accepted, but couldn't agree terms with the player. NO WONDER! The guy was about to enter the pitch for a WC Qualifier against Holland. All they had was 3 months to sort this shit out, FFS!
You can't make that shit up. And Arsene Wenger was in Paris, too. Maybe Dick Law missed another flight, so he decided to go talk to Lemar himself. I don't know... but the truth is, Lemar will play CL football with Monaco, and he wouldn't with us. It's over, Arsenal's and Wenger's appeal to top players has come to an end.
The only piece of good businness was shifting Ox for £40m (but we know only Kroenke will be happy about that, it won't make a difference to us).
Now we're left with a disgruntled star player for at least 6 more months, and let's not forget Özil is on his last year too, I'm thinking he won't sign a new deal either.
Now, on to football issues: Wenger committed the most basic mistake of man management last Sunday. He simply played 2 contract rebels against Liverpool, didn't he? By playing Alexis ahead of new signing Lacazette and Giroud, he made the dressing room environment even more toxic, letting down players who still want to play for him and leaving them to rot on the bench so that Alexis would play ahead of them. That sends out a bad message to the outside too, as it makes Arsenal look even weaker, overly dependent on Alexis.
The other contract rebel, Ox, was even more strange. Why play this guy at all? When his mind was elsewhere and especially considering all the compromises he had to make with team selection just to accommodate Ox on the right! We had Bellerin shifted to the left... all of this while Sead Kolasinac, that beast of a left back who shows such promise, was sitting on the bench, raring to go.
Just look at what Klopp did with Coutinho. That's the way to go about this business. Not only Coutinho wasn't hurt, he really caught the eye playing for Brazil yesterday. But when it comes to the club, he only gets to play if he's committed.
This is man management 101 really, which Wenger seems to overlook.
I won't even go on about the rest of the team, I think the pedestrian performance speaks for itself. The way those players behaved on the pitch is an absolute disgrace, they've let Wenger down big time, but Wenger isn't helping himself either.
I really don't know what will happen from now on, but one thing is certain: that idea that Wenger himself is the man to get the club out of this mess is becoming more laughable by the minute.
