His highly anticipated battle against Chris Eubank Jr. had to be cancelled when the 26-year-old tested positive for a prohibited drug.
Yet, the WBC recently cleared Benn after accepting his justification for the illegal substance found in his system.
Due to this, Benn even made a suggestion that he will fight Manny Pacquiao, a previous eight-division champion.
Benn was not afraid to criticise his opponent and said that Brook quit the sport the last time they attempted to get into a fight.
He wrote, "Must have been that sparring session." But Brook also responded angrily, insisting that Benn was the one who ended the session.
