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.
