Suarez in his pomp years for us and Barca was an absolute machine. Suarez was playing in a significantly weaker side than Salah as well during his time here.
Suarez prime years:
2012-2018 - 279 league appearances - 213 league goals.
Salah prime years
2015-2021 - 265 league appearances 149 league goals.
I wouldn't subscribe to the view that Salah was clearly a better forward. If anything it's extremely debatable.
I am reposting a post that I made in April 2018. This is a comparison of Suarez's peak season for us against Salah's peak season for us until March 6, 2018. They both have similar number of appearances .
"Salah has scored 32 goals in 38 appearances
Number of games with zero goals: 12
Number of games with one goal: 20
Number of games with two goals: 6
Goals against top 6 teams: 7
Suarez scored 31 goals in 37 appearances
Number of games with zero goals: 19
Number of games with one goal: 9
Number of games with two goals: 6
Number of games with three goals: 2
Number of games with four goals: 1
Goals against top 6 teams: 4 (3 against Spurs)
Suarez was more explosive and erratic. Of course, Salah is not the creative force of nature Suarez was but what struck me is his goal-scoring consistency. He has scored one goal in 20 games this season including against top teams.
There are gaps in Suarez's goal scoring in the second half of the season, particularly against top teams. As brilliant as Suarez was, Salah is something else. "
I don't think Suarez played in a weaker attack compared to Salah. Rodgers sold Carroll and crafted our attack to be centered around Suarez. The trifecta of SAS was something else that season. Suarez had Coutinho and Gerrard supplying him. Gerrard set piece delivery was particularly brilliant during that season.
