Costa is too erratic to be made the face of the club, it will never happen. He is the type of player who needs a strong captain to keep him in check. Azpilicueta or Luiz will be, they are leaders on the pitch, model professionals, great characters and never surrounded by controversy. I certainly hope one of them will represent my club once JT hangs up. Kante? Too quiet and shy, don't see a captain in him.
