The former Anfield star was disappointed by a collective lowering of standards within Jurgen Klopp’s squad during their last Premier League outing
Jurgen Klopp’s side missed the opportunity to open a five-point lead at the top of the Premier League table after being held to a 1-1 draw by West Brom on Sunday.
Liverpool took the lead after just 12 minutes at Anfield, with Sadio Mane stealing home after controlling a powerful pass from Joel Matip.
Reds fans would have expected the floodgates to open after this goal, after seeing the Reds dismantle Crystal palace 7-0 in their previous game, but the Baggies defended well to stay in the game.
Sam Allardyce, who was recruited to replace Slaven Billic at the Hawthorns earlier this month, set up with six players at the back to keep the reigning English champions at bay, which ultimately turned out to be be a masterstroke.
West Brom waited for his chance at the break as Liverpool grew increasingly frustrated and were finally rewarded when Semi Ajayi returned home with just eight minutes left.
The visitors picked up a point that increases their chances of breaking out of the relegation zone, with Warnock questioning the mentality of Klopp’s team in the second half.
“They all gave up on the gas and thought the game was won. They all thought it was too easy and they needed to do more, “the former Reds defender said on Match of the day 2. “I think the standards we expect from Liverpool fell in the second half.”
Warnock added: “It was almost too easy for them, wasn’t it? It was like a practice match in the first half. It was wave after wave of attack. West Brom didn’t really return anything because they were suffocated. However, you still thought Liverpool had to give more.
“With the way West Brom maintained their game plan, even after scoring a goal, that was what was impressive. Even when you get down on a goal, you wonder if you believe in what you’re doing.
“They were very brave in what they did.”
The EX-England The international then credited the Baggies with restraining the influence of Mane, Mohamed Salah and Roberto Firmino in the final third by sticking to tight defensive form.
“What it’s all about when you go to Anfield is you know you’re going to have to give up possession,” Warnock said. “Liverpool had 78% of the possession and West Brom had 22%, but they were so organized and setting traps.
“They stayed nice and narrow and left no space for Liverpool to break through and send balls to Roberto Firmino and Curtis Jones. They stopped the complex play of the first three and did it perfectly. They made it so difficult.
