This is becoming a bit like the Sarri-CHO situation from last season. I don't disagree that Pulisic needs time to settle in, adapt etc but getting left on the bench and not getting minutes - be it just even 20-30 minutes at this point - aren't going to do him any favors in settling and adapting to the league. But I guess if he keeps up that attitude, keeps working at it, he'll get there.
And speaking of Willian, with him suddenly getting so much game time this season - a turnaround from Sarri last season - I suspect that we will offer him a new contract and he'll stay for another year at the very least!
