The 66-year-old was heavily tipped to replace Fabio Capello last year, only for the FA to approach and appoint Roy Hodgson instead, and says his Tottenham contract forced the governing body to look for cheaper options elsewhere.
But Redknapp, who is currently battling against an ever-increasing threat of relegation with the Rs, says he would not accept the lure of the Three Lions job in the future.

"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."
After missing out of the England job, Redknapp then saw his contract at White Hart Lane terminated after failing to agree new terms.
It was thought that Redknapp failing to hide his desire to manage England had angered Spurs chairman Daniel Levy and led to his dismissal, but the manager says club owner Joe Lewis had the final say.
"Was it Levy who cut the cord? It was other people, the owner of the club that decided," he added.
