Arsenal is 8 points clear but at the same time, Manchester City has played one match less compared to Arsenal. Now I do not think it is going to be a good idea for Arsenal to take things easy. They will have to perform better if they want to be the English Premier League title champion.
Arsenal is now out of the Europa League and has no competition; they only have to focus on the Premier League; they are now eight points clear until their return from the international break, and Manchester City has one outstanding match to play; if Arsenal plays their remaining games as they did against Crystal Palace, they have a good chance of winning the League ahead of Manchester City.
I don't know if Manchester City is actually 100% interested to win the English Premier League title. At least I think they are not more interested in the English Premier League title this time, at least not more than the Champions League trophy. I think the main target of Manchester City is to win the Champions League trophy and finish in the top three of the English Premier League. And that gives Arsenal a little more breathing space.
Yes, Manchester City's main goal this season is to win the Champions League, but they are also interested in the Premier League. They will have to be very serious because they will be playing Bayern Munich in the Champions League, so they will have to focus on the Champions League more than the Premier League this time because the Champions League is one of Manchester City's top priorities.
