I'm sure it was on one of the YouTube channels (AFTV, TGT, Highbury Squad etc) that I initially mentioned this a while ago, but if it was in fact GW then I apologise for being unnecessarily repetatative.
I am of the opinion that some of the issue that Arteta has with Guendouzi and his like stems from himself having been a solid pro at the top level of the game if not as Mr. Terrence Henry would put it, the top top, top level.
The peak years of his playing career were spent at Everton who with all respect, rarely even glimpsed the highest echelons of the game back then, and why his arriving at Arsenal was like a validation of his own self belief that he was indeed good enough to be on the same pitch as some of the big hitters in the Champions League never mind those players who regularly were, that nowadays would be labelled as pubbers or farmers.
Remember, his peers were dominating club and international world football whilst he was like the kid who is last pick (technically not a pick) from the 20 boys lined up and met with murmerings and groans upon the 19th kid getting chosen.
That his donning of the cannon on his chest came 5 years too late is one thing, but that its weight left an impression on his heart like a tattoo, I have no doubts.
That being the case, to then watch this man cub be given opportunities he himself would have killed for, and then nonchalantly throw them away and act as though another one will be along in a minute or two like he's in a tube station, is probably a level of petulance that only his professionalism restrained him from ultimately receiving a police charge of GBH.
Similarly, when an academy graduate has an issue with playing for Arsenal in a full back position instead of their preferred or accustomed position, that it doesn't sit well with the Spaniard was always going to be the conclusion.
