2. Ashley Young

Young has served as interim captain in Antonio Valencia's absence this season, and is probably the favourite to take over permanently as well.
The winger-turned-right-back's consistency at the highest level is mind-boggling. In spite of several big money signings threatening his spot in the starting XI, Young has always been a regular for United.
Adapting from a winger to a full-back is also no mean task, and Young's transition has been almost effortless, especially considering the quality of the Premier League.
Full back is probably the most tactically nuanced and physically demanding position in football right now, and Young is still somehow first choice for United at the age of 33.
Under Solskjaer, he has also added an attacking output to his game, often making overlapping runs on the right and putting inviting crosses into the box.
He's also a great leader. In spite of not being a natural defender, Young has been brilliant in marshaling his defence under Solskjaer.
There probably won't be many complaints if he gets the nod.
