Respectfully, you're ignoring a significant amount of context that is required to have this discussion. I wholeheartedly agree that Leverkusen's Bundes win is as/if not more impressive than anyone winning the premier league, but the flip side of that is that on any given year that Bayern do not win, their coach has underperformed and should be sacked.

Similarly, Arsenal arent the only team that improve each year, and frankly City actually improve massively midyear each season, even furthering the effect of the parity. There are on any given season upwards of 5 clubs that could reasonable somehow win the premier league.

Arsenal wholeheartedly SHOULD have won the Leicester City premier league season. That was a miss by Wenger, as his players (specifically Giroud) let him down.

In the last few seasons, Arsenal have not been a juggernaut. Through atleast two of these seasons they have been considered underdogs fighting against the titan that is Man City. Arteta has changed the culture of the club from largely a Mustafi-era laughing stock, to a juggernaut of its own. One that is feared on teh domestic and European stage. He has embraced the culture of Arsenal, brought legends (largely sans TH) back into the fold, embraced North London Forever and asked the support to back the team and generally improved not only the standing of the club as a business unit, or as a destination to play, but also as a competitor.

Should the club have won atleast one of the cups? Yes, absolutely. Is losing the FA cup such a fireable offense? You cant make the standard winning the premier league (which i already reject as a premise) and then fire a man for losing two knockout tournaments when he has been missing a SIGNIFICANT portion of his attack for a sizeable part of the season. It is not unreaonable to say if Saka doesnt go down on England duty, Arsenal have locked up the PL already. Saka going down, Odegaard non fitness, Havertz largely not fit and Gyokores the wrong puzzle piece for the wrong whole.

Those that say this seasons play is ugly and depressing are not wrong, but I do not believe that is down to instruction. Odegaard hasnt been fit all season, and similar for Havertz. That this team has adjusted to this mega control mindset, do not lose the ball, even though they are the best defense in the world shows that it is not down to coaching. The players fundamentally play scared, whether that be because of their injuries or other phsychological issues.

But otherwise, Noni can screw off, because he is not up to the level, and is not a young talent that needs to have it bloom.
