In his column for The Sun, Redknapp wrote: "Ollie - who I tried to sign when I was manager at Bournemouth - has got his chance because he has grafted away with an unfashionable side and taken them up.
"It's one of only two ways a young boss gets a chance. The other is to take over a team who are up to their necks in the brown stuff. The opening-day win over Wigan had everyone blinking in disbelief. But the question now is can they keep it going.
"Euphoria from the 4-0 win at the DW Stadium will quickly disappear and the real test will come when Blackpool lose four or five on the spin. And that WILL happen.
"That is when Ollie will be put under real pressure and he will have to get his squad to react in the right way. Can he do it? I hope so as he is a real character, one of those blokes you would want to buy a pint for. We should all be looking at the Ollie factor as I know he will squeeze every last drop of effort out of his squad as Blackpool fans dream the impossible dream.
"The Seasiders are not a long-ball side but instead try to play good, creative football that some might find a tad surprising. That all stems from Ollie's trip to Holland during a spell out of work, when he studied new coaching techniques and approaches to the game.
"Blackpool fans - and maybe the odd anorak - will be able to tell you who the team's top scorer was last season. But, outside of that, I reckon most would be struggling to name half-a-dozen of their players off the top of their head.
"I've a feeling that, at the end of the season, those same names will trip a lot more easily off the tongue."
