Well, only by tomorrow are we going to know, even though I might want to agree that Arsenal is not entirely organized as they are supposed to be, I still will not want to agree that Manchester united will beat Arsenal, worst to worst, the game will end in a draw, this is the worst that can happen for Arsenal or maybe the both team, but then , Manchester united beating Arsenal is very unlikely.
But as I have said before, only by tomorrow are we going to know which team will beat the other, not underrating Manchester united's capabilities though, but I think a win is very important for Arsenal right now and that alone should motivate them well enough to take the lead in their tomorrow encounter with Manchester united .
It's tough for Man United to beat Arsenal at home, they have a bad record when they visit Emerates Stadium. On the other hand, this will be a proving ground for Arteta and Ten Hag, these two coaches spent a lot of budget to build the squad for this season. However, I predict Arsenal can secure full points at home, because Ten Hag squad is not yet very stable.
If true, it is reported that Rasmus Hojlund will make his debut during this match. Of course Hojlund will not start from the start, and he still needs to adapt.
