MU performance is not good also, I hear the news the defenders, Varane and Captain Maguire aren't fit because of injured when playing on the final Nations League yesterday. This could be a crucial weak point for MU, they lost a week ago because of that (without Maguire), they have good on the front but are very weak on centerfield and Back. While Leicester, all International players who have an action for their countries got the winner.
Maybe I can agree that United have temporary difficulties in defense, but definitely not with the fact that they are weak in midfield. I think that this is their strongest line and if it is normal then such a weak (relative to top clubs) opponent like Leicester will have no chance despite some weaknesses in United's defense. I think in this match United will be the clear favorite and will achieve an easy victory.
The defense has been their problem since the start of the season. On top of that, now that Maguire is injured, they will have a hard time on the defense. Maybe now is the time for Ole to try new formations. Maybe he can play 3-4-3 where he plays 3 central defenders and plays Shaw and Bissaka as wingbacks. Maybe that might help them a bit with the defense. Or maybe he could play McTominay and Fred both and defensive midfielder in a 4-2-3-1 Formation and resting one of Bruno or Pogba.
