I've said it before, United have to win twice, we have to win once. In footballing terms the ball is still in our court because we have to win our one game whereas they have to win 2 and they now have Martial injured who they have relied upon a lot.
Bournemouth and West Ham especially will not be easy games too for them the same Swansea won't. Lets not forget the other scenario, say United win all of their games, what if Arsenal get beat by Villa, that is still us in 4th assuming a win at Swansea. It will definitely go down to the wire no matter what happens and it would be typical of this season to throw up something like that.
