Correct, the race between Arsenal and Manchester City is better and more interesting every day because there is a harder way for Guardiola and his players to win the trophy, they need to reach Arsenal in the table and they will need to wait for Arsenal to make a mistake and give the ma chance in the other hand Guardiola will have hard games in the champions league which can make it hard for him to manage the players for both tournaments.
There is 8 point difference between Arsenal and Man City. It is still interesting to see how Man City can chase Arsenal. But I doubt that Man City can overtake Arsenal because Arsenal plays very consistently until now.
