With Manchester City still their competitor, they cannot be said to be champions yet. Their points gap is not too far and the Premier League still has enough games to make their position change. Arsenal just needs to maintain and continue to gain full points if they want to become champions. Because now they are depending on the results of their own matches with them leading the table at the moment.
Asernal is closer to the title more than Manchester city tgis season, even though man city is tge current title holder but the possibility of retaining that title is near impossible at this time and that is why we can project directly to Asernal taking over the title from them.
