If you're Romero, Bentancur, Madison or Bissouma, are you going to accept player of inferior stock as your captain? A player that is well below your level?
We have already seen how that donkey Maguire captaincy turned out for United, the likes of Bruno and Pogba were openly taking the piss out of him.
Anyone who has played football even at grass root level understands this, you never give captaincy to one of your worst players in the team as superior players will never respect and accept him as a captain.
