It is unclear whether Brentford is not in their best form or Liverpool is simply too strong for them but what is certain is that Liverpool played impressively and they deserved the win. It is quite difficult to compare the strengths between teams because the season has only just started and I think there are still some teams that haven't yet set up. However, the match against Man United seems to be able to be used as a comparison, whether Liverpool with their new coach and strategy is truly effective or whether Man United is the one who stands out with all the changes they have made.
So far Liverpool have not met a strong opponent so it is true that we cannot conclude anything about Liverpool's strength with their new coach but as far as I see right now there is not much difference from Liverpool's team performance moreover the players in their current squad are still the same as last season. And for the victory against Brentford in the second week it is quite worthy for Liverpool to get, that's because Brentford is not better in quality than Liverpool.
