I quite like the committee approach to captaincy — a tad bit like what Bayern are doing, or have done, over the years:

Especially at a club like United, where we currently don't have an exceptionally inspirational figure who ticks all the boxes — like Keane did in the past.
Cpt. De Gea: Best and most consistent player, and has been at United for 7 seasons
V-C. Valencia: Longest tenured first team player at the club, and an outstanding professional
2-C. Lingard: Local kid and academy product: has a good rapport with the younger lot, and United runs through his veins
3-C. Matić: Seasoned and apparently authoritative, and seems very devoted to the manager
