The reigning champions were beaten all ends up by Villa on Sunday in a crushing 7-2 defeat.
Liverpool were 4-1 down at half-time as an Ollie Watkins hat-trick put Jurgen Klopp’s side to the sword.
The Reds then capitulated further in the second half as goals from Ross Barkley and two from Jack Grealish inflicted the heaviest Premier League defeat on Liverpool in their history.
Speaking during his punditry duties for Sky Sports, former Liverpool captain Souness said: “What I would say, Villa, and it’s the same for both teams, I think they’ve left the grass longer than normal to slow Liverpool’s movement.
“All the top teams want short grass, a fast pitch. That doesn’t look like a fast pitch to me.”
Sky’s presenter Dave Jones suggested Souness’s half-time opinion was a case of “sour grapes” and a member of Villa’s ground staff team, Eddie Mills, has backed up that view.
“Graeme Souness’s uneducated comments about the villa pitch are insulting to all the massively hardworking groundsman up and down the country who put their hearts and souls into their proud work! #clueless,” Mills wrote on Twitter.
After the game Souness appeared to have changed his mind about the reasons behind Liverpool’s defeat, pointing the finger at three players in particular.
“When Liverpool got back to 2-1 having conceded two goals they didn’t rise to the occasion,” he ranted.
“A lot is going to be made about Liverpool holding a high line. That will never change. Liverpool will always hold a high line.
What was to blame for Liverpool’s shock defeat? Have your say below.
“You can only hold a high line when the rest of the guys are putting team on the ball under pressure. The minute you’re not putting the ball under pressure you have to start retreating back to your own goal.
“Liverpool’s problem started and ended with them not putting the ball under pressure. The midfield started with Fabinho, [Georginio] Wijnaldum, [Naby] Keita.
“They didn’t do their job tonight. Then they replaced them. The ones who came on didn’t do their job tonight.”
