Every match in the Premier League is a big game because you are not sure of taking the whole three points until you have played your match and won. Arsenal is already in the Premier League title race because they are in the third position in the Premier League table, with 43 points and two points behind the Premier League table leader.
I agree with what you say. The English League is really interesting to watch because they have an even level of competition between teams. Every English league match is very interesting and I admit I know more about the names of football players in the EPL than in other leagues. But even so, Arsenal still has a chance to win the title because they are only 2 points away from the top of the standings. The top 5 positions can still change because there is not that much difference in points.
Of course, we can see changes in the top ranks because the quality of the league is so high that even teams that are close to relegation can get points from the big teams. This suddenly changes the fate of the entire league. Arsenal still has the chance to win the title. They played one more match and their points are in good shape. If Liverpool and Manchester City drop points, Arsenal can get into the pot again.
