The Blues were beaten 4-2 by Phil Parkinson’s side in the FA Cup on Saturday, ending any hope Jose Mourinho’s side had of winning the quadruple this season.
However, his side could book a date in the season’s first major cup final this evening, and Babb believes that their manager will not stand for a second cup exit in the space of four days, and that could be bad news for his former team.
"It's always difficult to play Chelsea," he said.
"But particularly after that result which shocked the football world. They're a wounded tiger, Jose will have those boys pumped up for tonight, and he will not expect anything other than a victory. He'll have the big-hitters back as well - he rested nine at the weekend, so it's going to be a formidable task for Liverpool, that's for sure."
The League Cup semi-final second leg is finely balanced following the 1-1 draw at Anfield last week, with Liverpool failing to turn their overall dominance into a vital first-leg lead to take to Stamford Bridge.
Just like Chelsea though, the Reds were far from convincing in their FA Cup tie, drawing with Neil Lennon’s resurgent Bolton Wanderers side at Anfield in a goalless and less than impressive performance. That draw, and their lack of goal scoring chances, worries Babb ahead of tonight’s fixture.
"They just weren't firing on any cylinders,” he added.
“Maybe they had one eye on tonight's fixture, but you'd expect Liverpool - after the confidence they took from the Chelsea game - to come through that tie convincingly. But they couldn't score, and that worries me ahead of tonight's game."
