Spot on, Arteta was brilliant working with Pep, both worked well together. Don't know too much about Lillo, but we need his assistant not be afraid to put him right on certain things and tactics.I've long thought that Pep needs a Director of Football who'll challenge him robustly after nights like tonight. Creative tension if you like, where the coach has to justify his decisions or be told he was wrong in no uncertain terms. I don't think it works when the DoF is your mate. I wonder how much 'groupthink' there is among the coaching team.
