It’s not dead. We generally used that when Partey hasn’t been available. That single pivot role isn’t an easy one.
But yeah, that’s what Arteta wants to use and he made it clear early on in his interviews/pressers.
I think Lokonga will be the pet project during preseason for Arteta and co. get more familiar with the role.
Hard to tell as no-one wears non Portuguese football shirts here, unless you go down south you might find a few sunburnt English immigrants or holidaymakers.
