Liverpool had fallen 4-2 to Aston Villa on Friday evening, a result that left them fifth in the Premier League and in danger of missing the Champions League places altogether. Salah, who came on as a substitute at Villa Park and is leaving the club at the end of the season, posted a lengthy statement calling on Liverpool to recover their attacking identity.
Gerrard, speaking on TNT Sports, said the post caught him off guard and that the fact it was published at all was itself significant.
"Wow. Listen, that is extremely interesting. Mo Salah doesn't really speak much, and he doesn't tweet, and he certainly doesn't tweet like that. So I think that he's sending a message to the outside that things in that Liverpool dressing room are not right: the identity's gone and it's really hurting him to see it in front of his own eyes."
The Liverpool legend was blunt about the implications for the manager.
"That is quite damning to the Liverpool manager and the staff in terms of where this team's at. Crumbling is a strong word. It's quite damning, the timing. It's unusual coming from Mo."
Gerrard also reflected on the Villa defeat itself, making no effort to soften his assessment of what he watched.
"The performance last night was terrible, it was awful, it was difficult to watch from start to finish and it hurt me watching Liverpool last night. There was no fight, no passion, no pattern of play, no connection, they're not moving around the pitch together, individuals were miles off what I know they can perform at. Villa were better all over the pitch. They got what they deserved."
Liverpool's board are reported to be backing Slot to remain in charge for next season, regardless of whether the club secures Champions League football. The Reds face Brentford in their final league fixture, needing a result to guarantee a top-five finish.
