Maybe they have, but Arteta also knows that this competition won't be decided between Arsenal and Manchester City, but between the long fight between the clubs with the other amazing opponents. The aftermath has to wait.
For me, if I have seen the progress of this season, of course there are still two teams that are closely linked to each other in the fight for the title this season. And that could be between arsenal and Manchester city because last season these two teams provided quite strong competition until the end of the season in the race for the title. It could be that this season they will do it again because these two teams are equally strong and still have a pretty good run so far. It could even be said that they will swap places again in the coming weeks.
However, for arteta, he certainly knows how to beat Manchester City this season, so arteta has a better chance of maintaining Arsenal's concentration in the upcoming matches. In the premier League, only manchester city is strong enough because they have registered themselves as the strongest dominant in recent seasons.
