The 23 year-old took a half-page out of the Hackney Gazette in a bid to wind-up his imminent opponent.
Chamberlain’s ad contained several references to Okolie working in McDonald’s and pleaded with employers to give him a chance after he scores a planned knockout.
Chamberlain also labelled Okolie ‘The Sauce’ and referenced Big Shaq’s smash UK hit ‘Man’s Not Hot’ in the education section of the placement.
The pair of undefeated 200 pound fighters square off on February 3 at The O2 Arena in London, with the winner set to push on and gain a ranking with the WBA.
