#1 David De Gea

David De Gea has been United's best player throughout the last couple of seasons. He has been in the Premier League for about eight seasons in total and understands the game very well.
Leicester have the threat offered by Jamie Vardy up front and De Gea may be called upon to do what he does best; make saves. United have many a time shown vulnerability in defense especially since Sir Alex Ferguson retired but De Gea has often come to their rescue.
He has gathered much praise from teammates and rivals alike due to his impressive performances. The Spaniard will look to redeem himself after a subdued World Cup where he was at fault in some instances.
United supporters will hope that his confidence will remain high and he will replicate the kind of form shown last season that saw him named the Golden Glove winner and according to many people; best in the world.
