Former Burnley and Brentford defender Ben Mee says Wolves "sensed" Liverpool's weakness in Tuesday's game.
The Old Gold beat the Reds 2-1 to follow up Friday's win over Aston Villa.
"Credit to those Wolves players and credit to Rob Edwards," Mee told BBC Radio 5 Live's Football Daily podcast.
"I think the substitutions made a real big impact in the game. In the last 20 minutes they were magnificent.
"To go on and win the game after conceding the lead the first time was fantastic for them and it's a great atmosphere there when it gets going.
"When you're playing against a top side you want to find a weakness and if you do sense that you definitely want to go and exploit it.
"Liverpool didn't seem to have the pace, intensity and tempo of recent years.
"I think Wolves and Rob Edwards sniffed that out and sensed it as well with his substitutions that were really positive. They got after the game and believed they could go on and win it which they did."
