Redknapp was in the running to replace Fabio Capello before Roy Hodgson was installed as the Three Lions boss last year with the R’s gaffer saying he did not get the role due to his heavily back-ended contract when he was at the helm at Tottenham.
"I wouldn't take it [the England job] now, no. Not now, not in the future," Redknapp told Twentyfour7 Football magazine.
"That was my time, really, if I was going to get it. Last year there were a lot of things that went against me surrounding that massive contractual clause. People will always deny that is the reason, the FA couldn't say that and I won't say, but it didn't help me.
"I had such a badly loaded contract it was crazy, in Tottenham's favour. That's what you get for not reading your contract properly. It was a massive amount that someone would have had to pay to get me out of it.
"If they sacked me it wasn't so massive and that was a bolt out of the blue, a shock, I genuinely never saw it coming."
