The 70-year old says there is “every chance" his managerial career is over after his departure from St Andrews on the back of six straight defeats.
Former Tottenham boss Redknapp said: “I doubt very much whether it will happen again now.
“I'm a realist. If I could help someone somewhere, help a young manager, I'd love that. I did it at Derby with Darren Wassall and had a great time."
He continued: “I took over a team that got out of trouble on the last day of last season, they'd had two wins out of 25, they weren't good enough. It needed change.
“But unfortunately I couldn't get the players in that I was after and it went down to deadline week before I got a big influx.
“Then it was six players making their debut on one day, then three games in that week, so even working on the training ground was difficult.
“It's a shame I didn't have the chance to see it through but time is something you don't get an awful lot of."
