Pep Guardiola is smarter in implementing strategies when he has to face big matches, but it is not impossible for Arsenal to beat Manchester City, as proven when many predicted that against Wolves would be the next victory for Manchester City but it turns out the opposite happened and Wolves only had one shot on target which managed to become a goal because Wolves' other goal was due to mstake by a Manchester City player.
In fact, this season Manchester City is getting stronger, whether with additional players or not, they still have good statistics to continue winning trophies this season in the Champions League. I believe Pep Guardiola already has everything at this club, solid players and given the freedom according to what Pep Guardiola wants. However, facing Arsenal, which incidentally is one of the most stable clubs in the Premier League, is certainly a challenge for Pep Guardiola. Last season Manchester City was able to win easily. It's just that currently, Arteta has learned a lot from last season's defeat so there will be a little difference in Arsenal's game later.
Apart from that, Tottenham will continue to extend its winning trend so we will see Spurs temporarily leading the top of the standings if they manage to get full points over Town before Manchester City play Arsenal. And in my opinion, this match should not be an obstacle for Spurs. With such a big difference in strength, I'm sure Spurs will easily beat Town alone.
I don't see that Manchester City is getting stronger this season, but indeed Manchester City is a team that is quite consistent so they are still favorites to win the Premier League and also the Champions League, but we also have to assess other teams who are stronger this season compared to last season so that it is possible for this team, they can beat Manchester City, Arsenal, Liverpool and Tottenham, these are the 3 teams that at the start of this season look better than last season and this makes it possible for them to compete fiercely with Manchester City.
What is certain is that Manchester City this season will find it more difficult to win the title than last season.
