Arsenal have been very good this season. they consistently perform well. they keep going and keep winning every game. it was incredible. And regarding Manchester United I still doubt that I can win against Arsenal. maybe my assessment will change if tomorrow's match Manchester United can win against Leicester. because Leicester are not very strong. so if MU can't win in this match or can only hold a draw. then of course in the next match MU will lose when facing a much stronger arsenal.
Aston Villa have also not been very strong this season although Aston Villa did beat Arsenal last season when Arsenal were not so consistent with their form last season.
So that this season Arsenal have started to get a little easier to deal with every opponent who meets him in every game so they can get a win more easily and yes that is amazing for Arsenal. But I still want to see Arsenal against a stronger team in the Premier League this season because I'm still a little curious whether Arsenal can still win or not.
