After Arsenal's relegation from the Europa League, they are only focused on the EPL... With 8 points to spare against Man City, I think they will be League champions this season... Man City really have a lot of challenges where they need to perform well... I think the Champions League is more important for them...
We can say Arsenal as champions if Manchester City lose against Liverpool in the upcoming match precisely in April
But if Manchester City wins then Arsenal are not safe the race will continue maybe until the end of the season
Arsenal can be said to be safe if they leave Man city with a difference of 10 points.
