We all know that Arsenal is one club that finds it very hard to remain consistent with their impressive performances till the end of the season which is why they've never won the league since 2004. But for Liverpool, I don't see them suffering the same fate Arsenal have suffered in the last two seasons where they eventually finished as runners-up instead of winning the league after leading the table for a better parts of the seasons. Liverpool this season have been the best performing team in the league and I think there'll be the team that'll finally end Manchester City's dominance in the English Premier League.
That is one of Arsenal's weaknesses that is very difficult to eliminate, they always perform optimally in the middle of the season, but after that their performance slowly declines. Arsenal actually had a great chance to win the EPL trophy last season, but a mistake in one match gave Manchester City an advantage. Liverpool are very different from Arsenal, they have a winning mentality and this team has proven that they can win the title race if they attack at their best. This time Manchester City must be more careful because their rivals are no longer Arsenal.
Arsenal's problem in the last two seasons is indeed like that, they do not have a strong mentality to be able to maintain their position for the title fight so that in two consecutive seasons they were defeated by Manchester City in the title fight at the end of the competition.
And it is true as you said that for this season Manchester City is no longer competing with Arsenal and even if you look at what is happening now the Arsenal team is no longer favored to win the Premier League title this season because they are indeed quite bad this season, although there is still a long time for them to rise but I think it is very difficult.
