Gerrard took issue with Slot discussing Marseille's "low block" for last night's Champions League win at Marseille.
He said on TNT Sports: "He needs to stop mentioning low blocks.
"Low blocks have been happening at Liverpool since I played and many, many years before me. That’s just the way it is, teams are going to try and do everything they can to stop Liverpool.
"The key is finding solutions. You’ve got the players. Then you’ll turn the low-block games into wins rather than draws. It’s not going to change.
"They’ll face a low block at times against Bournemouth at the weekend. They’ve got to be ruthless and the big players have got to step forward and score the goals to win games."
Gerrard was reacting to Slot stating post-match: "I know so well why we are not consistent. That mainly has to do with when a game is more open, when players can players can play through the lines and tactics are involved and they show how good they are, that's completely different than against a low block.
"You need a completely different quality against a low block. Against a low block, it doesn't have much to do with what you prepare before the game. You just have the ball a lot, get in the final third, and something should happen."
