Left on the bench for Liverpool's 3-3 drawat Leeds, Salah spoke to reporters afterwards, claiming "someone" inside the club wants him out and also declaring he has "no relationship" with manager Arne Slot.
On Monday, Carragher said on Sky Sports: "I thought it was a disgrace.
"Some have painted it as an emotional outburst. I don't think it was.
"When Mo Salah stops in the mixed zone - which he has done four times in eight years - it is choreographed with him and his agent to cause maximum damage and strengthen his own position."
Carragher continued: "He has waited, I think, for a bad result with Liverpool.
"Everyone connected with the club feels like they are in the gutter and he has chosen this time to go for the manager - and maybe try and get him sacked.
"The one line that stands out for me was 'thrown under the bus'. He has tried to throw the club under the bus twice in the last 12 months.
"Going after the owners initially, he complained a year ago because they hadn't given him a contract at the age of 32.
"With the manager, he should be doing all he can to help the club get out of the worst run of results they have had since the 1950s."
