That's what to watch out for because Tottenham are in the middle of their peak with Antonio Conte with 2 very deadly strikers "Son & Kane" I think this will indeed be a threat to Man United even if it plays at Old Traffor, so my chances are more on the result draw or Tottenham can win.
Son, Richarison and Kulusevski are always troublesome with their runs which are quite difficult to catch. On the other hand Kane is also in good form and found his good form after missing last season which makes Tottenham now cannot be underestimated.
Currently Manchester's midfield is also still a little difficult.
Even though Ten Hag does a lot of schemes that are actually meant to strengthen in the midfield, but as you said, currently Ten Hag is still not able to maximize the potential of the MU players well.
