One of the reasons Arsenal is always having a lot of advantage but is having trouble keeping up with the play is because those who look down on Arsenal are just jealous of Arsenal's performance and all they anticipated from Arsenal is to fail. However, they do not see Arsenal failing. Since Manchester City was fortunate enough to have earned a lot of points from their previous season's play, that season was significantly more favorable for them than it is for Arsenal. And the fact that Arsenal was losing games at the time gave them a significant advantage. That is were it is getting difficult Manchester City and Liverpool been involved the opportunity like last season won't be there again now we have to really work hard to win the title. The games we have ahead we are going to succeed.
This is a more or less even season for Arsenal, without obvious declines, and Liverpool is holding up quite well this season, but this is not a constant state of affairs for these teams, but for City this is normal, they spend every season at a very high level and if this time is very high competition, this does not mean that everything will be the same next season. Klopp will leave Liverpool, the new coach will rebuild the team to suit himself, and Arsenal have a long-standing problem when they go through periods of downturn...
Arsenal is having a pretty good season this season but they don't know yet whether they will survive until the end of the season to continue to challenge for the title of the top three teams. If Arsenal makes mistakes again like last season then they will fail to get it again, while Liverpool and Man City still look consistent. At this time and trying not to be careless, Kloop will leave Liverpool at the end of the season, therefore he will give his best strategy one last time.
Arsenal had a good performance and got good results in the last season. In fact, they usually start the season well but time after time the other team, and specialty Guardiola and his team will start racing with them. I think the most important thing for Arsenal to do is to try to have stable performance in the games they are going to have until the end of this season otherwise they will again lose their place to Manchester City.
However, Arteta is not more experienced, and considering the budget and improvements they had so far I think Arsenal can have more chance to win the Premier League at the end of the season.
The thing about Arsenal is now they are playing in the Champions League and the Premier League at the same time and can put more pressure on the team while Arteta should manage his team in this situation.
