In any team, regardless of who gets the arm band, there is always someone organising the defence, someone organising the attack. Maguire has obviously failed on the former, which I thought has been taken over by Varane, but we see Casemiro and martinez stepping up. You don't need an arm band to step up BTW. Bruno has been doing that on offence, eriksen is another one.
As you mentioned able to deal with the press, is an important criteria for Captain of the team. IN fact, this applies to fans as well, I wonder how much the tide would have turn if Bale can speak fluent Spanish, and perhaps join the late supper instead of going to bed early for morning golf....
p.s. what about Rashford, an old timer? Is there a bias against local boys? Shaw, AWB, Sancho, are not there neither?
