Not sure it is any worse than some of the early Emirates teams in the periods post Henry.
We had some fúcking corkers playing for us in that time but arguably the overall standard of the PL was lower which allowed us to make top 4.
There are some excellent footballers in the current team, the issue is the manager.
He had an handy excuse of Chelsea being big spenders
'we can't compete' and we just moved stadium.
Though those squads still played exciting football. The whole period where we had the likes of Arteta (I like him) Squlliaci, Jenkinson, Frimpong, I didn't like at all.
we were not that great last season at Highbury either to be honest except our decent CL run.
Those teams had smashing individuals such as Fabregas and van Persie but some of the others around them should never have been allowed to play for Arsenal such as those you name.
The current side also has smashing individuals, more I would argue, but perhaps a manager who doesn't appear to be able to get the most from their assorted talents.
Win the EL and he stays, or he might go in a blaze of secondary glory.
No idea.
I would honestly doubt MA is going to leave Juventus for a club that is not even in the CL so while EL success may work in your favour here I also suspect it would be the catalyst for further Wenger.
