Utd's next three games are massive: Liverpool, Arsenal and your lot.They don't have the quality. GD is still - IMO - the best measurable statistic to tell you about the quality of a team over a large period of a season.
4th is done - Arsenal had to capitalise on Tottenham losing and didn't. United have 3/4 games left they can't and won't win.
Your league campaign could be totally finished by the time that you play them, though.
If you beat Arsenal and West Ham and the top 2 also win, then you'll have nothing to play for.
Tuchel may choose to rotate and experiment, though it might be too big a fixture for that.
