Not sure about that. I hope Arteta isn't too stubborn for his own good. Seems like he's trying very hard to imprint his vision with select personnel and traits, all preconceived. Basing this off Mari, Soares, this rumor plus his use of DLPs and full-backs. Needs to (if he isn't) take into account his scouting network and the way the league is shaping as well. Otherwise he's capable of falling into the same traps as Emery, namely failing to translate theory to effective practice. Or perhaps this is Edu/Raul showing signs of convenience again.
The only plus I can think of is that Willian still has a bunch left in the gas tank, having been inconsistently used by Conte, Lampard and Sarri.
