Since Sadio mane left Liverpool to another team has really changed Liverpool negatively, because it hard Salah to perform well in this season compared to last season, because the player that really understood him is Sadio mane that left the team last season.
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.
