Britain plays host to its first ever unified world title fight, as Bellew once again prepares to shock the boxing world - but what are the keys to victory for both fighters?
TONY BELLEW faces the biggest - and final - challenge of his career when he takes on Oleksandr Usyk for the undisputed cruiserweight world titles.
Bellew defined the odds when he overcame arch rival Nathan Cleverly in a rematch, rose from the canvas to snatch the WBC world title of Ilunga Makabu, and stepped up to heavyweight to defeat David Haye, twice.
Here SunSport explores the keys to victory for both fighters, and my final prediction in what is a historic night for British boxing, as it hosts its first ever undisputed world title fight.
The former WBC champion possesses a better boxing IQ than he is credited for - and this was on show in his rematch against Haye.
Bellew (33-2-1) (20) must deploy the same strategic gameplan he showcased in May, as he allowed Haye to commit to attacks he could read and then come back with counters.
Usyk is a formidable boxer who likes to get in a groove through making his opponent come forward and stepping in and out of range firing well time counter attacks.
This was showcased against Murat Gassiev in the World Boxing Super Series final, as the Russian was simply outclassed.
Bellew must not come forward with needless aggression throwing big shots early - like he did against Makabu where he found himself on the canvas in round one.
Makabu fell victim to a brutal Bellew left-hook that night, but the Bomber learnt from his lesson against Haye in the rematch as he adopted a more patient approach.
Bomber needs to put Usyk out of his comfort zone by letting him come forward and throw more shots than he would otherwise do and set up the opportunity to land a big left-hook.
Once Bellew breaks Usyk's rhythm he can pounce on his opponents need to overthink and dictate the fight with his jab and force his man back .
But of course, the counter left-hook could be the decider for the proud Scouser.
Usyk
For a cruiserweight Usyk has incredible footwork, something he has mastered with his friend and countrymen Vasyl Lomachenko .
However, while the quick feet looks easy on the eye, it's also a key component to the Ukrainian's success.
Usyk (15-0) (11) has to establish a rhythm early on - he has showcased the ability to throw combinations with fluidity while stepping in and out of range at just the right time.
When Usyk is able to relax and let his punches go, like against Gassiev and Marco Huck in the WBSS he is hard to break down - however, in the tournament semi-final, Mairis Briedis forced The Cat into a brawl and made the affair tight.
Usyk cannot afford to be dragged into a war in mid-range, like against Briedis as this will be where Bellew can exploit his power - the Ukrainian has to keep the action at range and set everything up behind his southpaw jab.
Usyk needs to keep on the move at least flicking out a jab before looking for combination punches, as Bellew showcased against Haye and Makabu when the opportunity to sit down on his shots and trade leather comes, the Bomber can take his chances.
Ultimately, it comes down to the old cliche - there are levels to boxing.
Arguably Bellew is the most improved British over the last five years, as his ring generalship and boxing IQ has become equally as impressive as his already destructive power.
However, I believe he is dealing with a modern great and pound-for-pound superstar in Usyk - and entering this fight Bellew is not regarded as a P4P contender.
So it is hard to bet against Usyk, who has proven to be one of the best fighters on the planet with an Olympic gold medal and undisputed cruiserweight world titles to back it up.
My prediction is an Usyk points win, as I believe Bellew has the capability, like Breidis, to push the Ukranian all the way and win at least three or four rounds in the process.
I think at this point Bellew is the world's second best cruiserweight - but unfortunately, I think he is facing the No1 in the division.
