Arsenal has no problem, they are to only avoid injury
They found ways to beat both small and big clubs
The only club difficult for them has been City, even all this while with Liverpool beating them they finally won against liverpool
They have a clear chance to win the league
The only threat arsenal has to stop them from winning the league is Manchester City, Manchester City are their biggest fear. I can see any team that can stop arsenal from winning the league this season. Arsenal has a different of 9 points from Manchester City, with this they are almost close to win.
