The Tottenham boss, understandably disappointed after seeing his side held 1-1 at White Hart Lane, famously said 'my missus could have scored it' in regards to the spurned opportunity.
Redknapp now accepts that lambasting Bent did more harm than good and insists he will refrain from making such comments again in the future.
"I must admit myself I think I made a mistake after one game, I did cane them a bit," he said.
"I didn't get a response from that, and someone I respect told me that wasn't my style.
"I criticised a few of the players and it really doesn't work for me, it's not really the way I manage.
"I get more out of the players by telling them what they can do rather than what they can't do. That has always been my way. They responded (but) I felt that was a mistake on my part. I felt I rectified that and lifted them and we've gone on from there."
AdditionsRedknapp has helped to usher in an exciting new era at Tottenham, quickly papering over the cracks left over from Juande Ramos' ill-fated spell at the club.
He now believes that Spurs will be realistic top-four contenders next season, with a few minor tweaks to his squad all that is required to have the club challenging at the top of the table.
"I think this is the club to play at, there are only the top four, other than that they couldn't do any better than Tottenham," said Redknapp on possible new recruits.
"It's a club going places and we could have a great season next year. It's a squad capable of pushing the top four.
"We need a few new additions in a couple of areas. They are the areas I want to improve."
