The former manager also believes the side are desperate for the return of striker Daniel Sturridge.
The German elected to go with a midfield of James Milner, Emre Can and Joe Allen, with Philippe Coutinho playing further forward, but none of those players were able to create many clearcut chances for the Liverpool forwards.
That has been the story all season for the Reds and Redknapp believes that is because their midfield is average at best.
"There’s no creativity in midfield; it’s an average midfield at best," he told BT Sport.
"There’s no flair in there or someone who can make the killer pass. There’s real work to be done.”
The former Tottenham manager also believes the Reds are in desperate need of a Daniel Sturridge return as soon as possible, as they continue to struggle for goals.
The Liverpool striker missed the majority of last season through injury and has also been absent for most of this campaign - but returned to star in the 3-2 win over Aston Villa.
He has picked up another knock that has forced his absence in recent weeks once again, though, and Redknapp says they desperately need him back.
"They are well short, they need Sturridge," he added.
"He’s that one player that can open defences and do something special around the box by creating goals and scoring goals. Other than that I don’t see anybody there who’s got the ability to do that."
