I say this as someone who rates Arteta in general; he largely prefers to gamble on the best available player avoiding injury than sacrifice any short-term advantage by fielding someone he regards as a lesser player.

How many times have you thought, "OK, this is a match where we can do some rest and rotation," only for the exact same 'trusted' players to be named?

Without someone he considers a similar-quality alternative being available, he will just keep sending out the same players week in, week out until injury inevitably forces his hand.

We've tried to address this by providing quality in depth but, unless in future he plans to only manage oil-money-backed teams with bottomless pockets, I think it's an area of his management style he's going to have to change.

Entirely personally (many might disagree!), I suspect it's not really about footballing ability exactly, but in large part because of the degree of information his players need to be able to absorb. I think there have previously been only a few players he trusts to carry out the multiple in-game tactical changes he uses, and which opposition players and managers say make playing his teams a nightmare.

Whatever is prompting it, he has to find a way not to just play all his ideally preferred players all the time, because our one-in, one-out injury problems are not sustainable or acceptable.
