Paul Gallen: former Australian NRL star ahead of boxing match against Sonny Bill Williams - Heather du Plessis-Allan Drive

Paul Gallen is speaking out after things got heated between him and Sonny Bill Williams ahead of their high-profile match in Sydney.

The pre-fight press conference initially saw both fighters seemingly ready to skip the verbal jabs in exchange for the in-ring shots on Wednesday.

However, the latter stages saw Gallen accuse Williams of drug use - and for charging large sums for his community work. 

Gallen says he can't see himself breaking bread with Sonny Bill after the fight, but 'that's life'.

"There's no acting going on at all - we don't like each other."
