Of course there is a possibility of Arsenal wining this premier league because right from the beginning the club I have in mind that could possibly win the premier league is Manchester City and Arsenal because there performance is extremely impressive and the competition they both had last season will still happen again this season because they both have all it takes to win the premier league.
But however the challenges Manchester City is currently having is the injury of there key players, which there absence has really affected the performance of the team but however I believe with time they will come back and when they do they will become unbeatable.
It's still too early which team will win the English Premier League, it's still only the 9th match, indeed every top team has a chance or opportunity to win the league. Injuries to players in the team mean there is a slight difference in the core squad, This is the job of a coach, how to play his role in dealing with injured players. The coach definitely knows the potential of all his core and reserve players. Even though the top 4 big teams are in their best performance, this will be a battle to maintain their position in the standings in the future.
