20 goals create in 8 matches is an extraordinary achievement for Liverpool's front line, even it is included in the top 4 of the GF premier league after Man City, Arsenal and Tottenham.
So I think Liverpool's main problem is not attack or Mohamed Salah. Because we can see how weak Liverpool's defense is until the 8th week of the Premier League with 12 conceded, very much different from last season which only conceded 26 goals in 38 matches.
In statistics, there is such a technique - to cut off the upper and lower 5-10% of some data under study in order to remove the influence of anomalous fluctuations. If we remove the anomalous game with Bournemouth (9-0) from Liverpool's statistics, then Liverpool's statistics become faded and the goal difference is even negative. Therefore, I would say that Liverpool have problems with the attack too.
