Funnily enough just been discussing this with my mate
We basically agree that Arteta is scared to change the system despite not having the players available to make the system we are playing tenable
I had to literally screen shot the subs from Friday’s game with Southampton…he simply couldn’t process why we’d start Vieira when Jorginho was available
I explained the only possible explanation for it is because Arteta won’t change the system therefore has to have a number 8 in there (and the “need” for an inverted left back meant that he didn’t play Zinchenko as a no 8)
I understand to a degree the hesitancy to change the system this late on in this system but it’s no working…something needs to change. And in my mind we should have a back up system to factor for injuries to begin with.
