So far I like how Liverpool plays without Klopp, maybe this is still Klopp's work and for now Slot don't have a greater impact on the team, but so far I do not even rule out that Liverpool will be able to start this season well. If they can beat Arsenal, no matter that it is a friendly match, then this is a good indicator. And maybe Slot will become the discovery of this season and will be able to compete with Liverpool against City and Arsenal. At least Slot did not make any cardinal changes in the team, so we can see the same team.
Slot seems to be able to adapt easily to Liverpool after seeing them beat Arsenal, even though this is only a friendly match, it cannot be denied that Slot has found chemistry with Liverpool's players. Indeed, both teams have not fielded their best squads, but Liverpool are filled with more young players in the match, of course if Liverpool play with a complete squad, Liverpool's performance could be even better. I can't wait for the EPL league to start, because this season the potential to compete in the EPL league has changed besides Man City and Arsenal, Liverpool is also participating even though with a new coach, Liverpool's performance is still as strong as when coached by Klopp.
In this friendly match, Arsenal's attack line was a problem, even though they dominated the midfield. They looked hesitant and slow in attacking. Maybe this is what Arteta needs to fix before the league starts. I am also curious about Arne Slot's orientation at Liverpool at the end of this season, is it Possession Football or Ball Possesion?
What you said was very visible in that match, the Liverpool players seemed more free to play the ball and they were even able to make Arsenal have to work hard to score a goal in that match, although the friendly match did not reflect the true strength of the two teams because neither of them fielded the main players in that match, but as a new coach who had not adapted well to the English league, Arne Slot was able to show Liverpool's style of play which was attractive when attacking and very solid when defending so that the Arsenal players had difficulty getting an equalizer in that match.
I don't know whether Liverpool or Arne Slot are only able to talk a lot in friendly matches or whether they will bring a better team to compete in the Premier League next season, but Looking at their game when they beat Arsenal, I actually see that the attack applied by Arne Slot is skewed built through the midfielders and it is the same as Feyenoord's previous playing style, so I think if that is what Arne slot will implement next season in official matches then now they have to really improve the quality of their central midfielders.
