I finally watched this cringefest and to my surprise Arteta wasn't even the biggest Captain Cringe on the show. That title goes to Carlos Cuesta hands down. Imagine going to work and this guy giving you advice, holy shit. Honourable mention to Mikel for that lightbulb and Josh for his hugs though.
Apart from the massive cringe, I mostly found the documentary incredibly boring. There was almost zero interaction with the players on a human level, we basically only saw Xhaka's home and that was immediately the most interesting part of the show for me.
A shitty failed PR push befitting the garbage club we've become. But I guess it resonates with a certain audience, probably the same people who read arsenal.com's excited tweets.
