For the past two seasons, Arteta has been consistently good at competing head-to-head with his master ''Pep Guardiola", and this season, he is to challenge Pep Guardiola yet again for the Premier League title. Who knows whether this season, Arteta will prove worthy to beat his master over the Premier League title before Pep leaves Manchester City in 2025. Although there are reports that Pep Guardiola will leave Manchester City in 2025. However, this season makes it to be his last season as Manchester City coach. That means the reign of Manchester City dominating the Premier League will be over as Arsenal takes over from Manchester City in lifting the Premier League title because it is only Manchester City that is stopping Arsenal from becoming the champions of England.
Arsenal's one true obstacle in winning the league is Manchester City, this is an unannounced fact. Pep's former assistant Mikel Arteta is Pep's biggest rival for the league, probably for the 3rd season in a row now. You gotta praise Arsenal for their growth though, they definitely came a long way. Now for the Gunners to overcome everything and win the league, they have to stop being defensive against bigger teams and have to play like winning teams.
I think yes, City is the biggest problem for Arsenal, and if they can overcome it, they can definitely win the league.
It has been shown that Manchester City is the problem that Arsenal always find hard to solve, which is like a blockage for them to the trophy, but based on the games that Arsenal have been playing this season, it shows that they will make sure they solve that problem. I know Manchester City will try their possible best to get the trophy, and Pep Guardiola will try his possible best to still maintain his position of winning the trophy, but as you said, if Arsenal can play games like a winning team, it will be very easy for them to get it to the trophy.
Because based on how the game is going from the beginning, Manchester City has already made it to the top of the table within 3 games, so I can say they are getting themselves ready for the trophy, but I know even if Arsenal were not able to get the trophy this season, Liverpool will do that.
