Just accept his limitations and use him as an impact player from the bench, midfield or LW depending on the needs.
He won't be here next season, no point in forcing him into the team. And definitely not worth building the team around him.
Absolutely this.
Wherever you play him, there's a massive downside. On the left we saw Shaw overrun yesterday. When we played Liverpool last season, TAA exposed him. We can't press effectively with him in Rashford's position. Defenders can play a higher line with him further forward.
Through the middle, he doesn't track opponents and loses the ball often, while slowing down transitions on a lot of occasions. He is a liability in his own box.
That's not to say that he isn't capable of producing a match winning contribution, but a team is only as strong defensively, as its weakest point, and he is it in most games.
Let's concentrate on the future, as it's apparent that he won't (and shouldn't) be a part of it.
