Thought De Gea would have been a decent shout. Been at the club long enough. Perhaps the leadership qualities that are required of a captain (understated these days?) aren't present in De Gea. Maybe Mata as well.
The fact it's been given to Maguire already goes to show that Utd have lacked/been lacking a proper leader for some time. I know there's the unhappiness at the board to explain some things about Utd right now but it could explain why some things on the pitch haven't been going great either - there's no character like you had with the likes of Keane, Vidic, Ferdinand, Rooney etc. Instead you have tits like Jones, Bailly and Fred to get you through
