Man City is always a good and hard contender in EPL and every time few mistakes are made by Man City but other top teams overcome their errors and loss points and games at a very crucial time which puts City on top of the table and this is the momentum which top team wants and they clinched the title.
Last season there was actually a moment where it was beneficial for other teams to seize the title from Manchester City, but at the same time they also experienced a problem and had to achieve several unsatisfactory results. as experienced by Liverpool. Liverpool is a team that is expected to break the dominance of Manchester City and they have that opportunity. But unfortunately they had to experience something unwanted when the season was about to end and it happened in crucial matches. Even they had to accept unsatisfactory results when they faced a team that on paper they were very favored.
Arsenal under Arteta's era doing very well the way team Arsenal improved their game and the way they challenged top teams previously for the title race is good to see.
Everyone hopes that Arteta's and the Gunners want more good results this season and want to lift the trophy.
I believe Arsenal will do better this season, I don't think Arsenal will disappoint their fans at the end of the season like they did last season. Last season, Arsenal lost both at home and away against Aston Villa, but this season we have seen some changes in their performance, Arsenal defeated Aston Villa with a clean sheet, so I am confident that this season will be different from previous seasons.
If you mean disappointing in the sense of failing to win the title, personally I can't say they won't disappoint their supporters, because this is just the beginning of the season which is still a long way to go until the end of the season. Moreover, we don't know what problems they will face, I don't expect that to happen, but in football there are always surprising things, one of which is a problem that might hit a team, such as a storm of injuries or other things. For now, Arsenal does look better, they have enough capital to go through this season very well. It depends on them, whether they will be consistent enough, especially when they have a problem.
