A rematch was expected only for Fury to pull out due to being declared medically unfit to fight.
Klitschko would never get the chance to avenge his defeat and instead fought Anthony Joshua in 2017.
The Ukrainian retired after his brave loss to AJ but has since teased fans about a comeback to beat Foreman's record as oldest heavyweight champion.
"Big George" was 45 years and 299 days old when he beat Michael Moorer to win the WBA and IBF straps. And Krassyuk believes Klitschko could also be eyeing up a piece of history.
"He's much stronger than he was 15 or 20 years ago, he can do it," he added.
Klitschko hints at comeback
It comes after Klitschko put boxing fans on red alert following a social media post on his return to the gym and sparring.
Having previously posted photos of training with Oleksandr Usyk during his transition from cruiserweight to heavyweight, Klitschko teased the boxing world about making a comeback to the sport.
In his most recent post, the heavyweight legend posted some sparring session photos on Instagram with one of the captions saying: 'Challenged accepted.' In the comments, some fans have speculated about the Ukrainian preparing for potential rematches against Fury and Joshua.
