Tottenham Hotspur were only able to claim a point against Liverpool in a 0-0 draw on Saturday.
Spurs struggled to break down a stubborn Liverpool defence, in a game where opportunities were at a premium, and the match ultimately petered out into a 0-0 draw.
Tottenham's two best openings in the game fell to Harry Kane and Clinton Njie, but it was a fixture where defences dominated.
And Redknapp said: "Tottenham were solid enough today, but they didn't create enough. That was the problem. There weren't too many positives for Spurs today, their performance was nowhere near the quality of the one they put in against Manchester City [where they won 4-1]."
Redknapp did manage to find one positive from the game, though, as he was impressed by the display of Mousa Dembele.
Mauricio Pochettino's recalled the Belgian international to his team after a spate of injuries, and he put in an assured performance.
"Dembele did excellent today in the holding role," Redknapp said. "He got on the ball and made things happen, and that was a positive for Tottenham."
The draw means that Tottenham have now extended their unbeaten run in the Premier League to eight games, and they currently sit in seventh place in the standings.
The Lilywhites' next match comes against Anderlecht in the Europa League on Thursday evening.
