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.
True, even though Arsenal are already in first place in the standings, all this is still not over, they still have to show their best match against Leeds next week. I assume Arsenal will appear violent against Leeds to get 3 points, considering the last matches of these two clubs were full of drama and counterattacks.
If Leeds manages to get 1 point and draw, I don't think this is too bad for Leeds who are still at the bottom of the table and I'm sure Arsenal will be able to win this match.
