David Haye and Tony Bellew meet on Saturday night in their highly-anticipated rematch at London's O2 Arena.

Who did they each beat last time?
Haye's last win was a knockout victory over Arnold Gjergjaj back in May 2016.
Bellew's last victory -- apart from his first triumph over the Londoner -- was against BJ Flores in Oct. 2016. He successfully defended his WBC cruiserweight title in the process.
Who is the favourite to win this time?
Haye remains a firm favourite despite his loss in the first fight, and can be backed with odds of 4/9 at bet365.
Anyone backing Bellew to repeat his heroics from the first bout can get him priced at 15/8 at the same bookmakers.
What is at stake?
Nothing's at stake, besides bragging rights. However, as Haye's said himself, if he doesn't beat Bellew convincingly he will retire from the sport.
