Ruben Dias changed the entire aura of this team when he came back. That's your answer.
Agree, but he did it without being captain, so it's not necessary.
Look at the players we've had as captain recently - Kompany, Silva, Fernandinho, Gundogan. I maybe wouldn't have put Silva or Gundo down as typical captains beforehand, but they led well and always showed up.
They've all been senior players when appointed, it seems to be the way we do it and it works with the rest of the players. It feels to me like it would be wrong for Kev not to be added to that list of captains.
Dias will get his turn and may become the best captain we've had, but for me, he's got to wait his turn still first. Two years for Kev, then Dias for maybe 6 or 7 years after that.
