Looking at how Arteta uses his players , it’s evident he believes in the concept of ‘optimisation’, making full use of the current resources one has . Sure he must feel bad , but he definitely won’t ‘sulk ‘ or keep complaining of the deals that didn’t happen for too long . I’m damn sure he’ll be positive about people like sokratis, kolasinac, Mustafi, Saliba and use them in Europa league , cup games and even u-23’s for Saliba . He’ll make full use of what he has until the jan window . If Nothing much happens in the Jan window , but he’ll be optimistic as he always is.
It’s a great quality to have tbh.
