Yes, indeed now they are 6 points ahead of Manchester City, but Manchester City has 1 game yet to be played, and if they can win that match, they will reduce the gap to 3 points. And if we look at the rest of the clubs they will face, Manchester City have fairly easy opponents from Arsenal, while Arsenal still have some tough matches.
That possibility still exists, that's right. If Man City can win next, then the difference in points will be even smaller. So there is still a chance for Man City to take over Arsenal's position. Later there will be a match that will certainly be very influential when Man City against Arsenal. It will be like a betting round for their position. And Man City will probably insist on winning, unless for some reason especially the UCL.
That is why Arsenal must continue to win in every remaining match before facing Manchester city and after. The two matches that Arsenal will face before facing Manchester city are against West Ham and Southampton. and I think the victory in these two matches will likely belong to Arsenal. because the comparison of strength with the two teams is very different this season. but Manchester City also has two fairly easy matches before meeting Arsenal, namely against Leicester and Brighton. against Leicester it probably won't be difficult for Manchester City but I think Brighton can make it a little difficult for them.
