Redknapp's stock has never been higher after leading Spurs to the Champions League, a triumph that ironically went a long way to getting Benitez the sack on Merseyside.
And Redknapp could be tempted away from Tottenham, with friends revealing he is upset that White Hart Lane supremo Daniel Levy has not approached him about a longer and improved contract.
However, there is also the lure of Liverpool, who have the kind of big-name history and glamour that Redknapp has always fancied - and at the age of 63 he is unlikely to get one of the established giants calling for him again.
Redknapp could have to uproot from his Dorset base - a domestic problem that has stopped him moving north in the past - but a two-year deal on top money may ease that pain.
And Redknapp can also count on his friendship with Dalglish to help open the door and make him welcome, with friends claiming he is willing to chase the job.
