Too soon to say whether Arsenal is going to win the title or not. They are in first place in the table and in the next week they will play against Leeds which is an easy game for Arteta and his players because they already won the last game they had against Leeds this season, also during the last games they had, Leed couldn't perform well enough while Arsenal got almost every possible point.
Leeds is not an opponent who can make it difficult for Arsenal, but Arteta must instruct his men to perform optimally. Arsenal must take advantage of the game against Leeds to get full points, they cannot lose points against weak teams. A win must be obtained as a good capital against Liverpool in the next match, after that there are still several tough matches that Arsenal will face.
It takes a lot of confidence to keep its position safe in first place, right now it cannot be said that Arsenal can win the EPL title because anything can still happen in the last 10 games.
