1. Date of birth: 3 June 1967 (Berlin, Germany)
Weight: 12st
Height: 5ft 10in
Division: Super Middleweight
Professional Record: 33 fights, 33 wins (seven knock-outs)

German boxer Sven Ottke has won all 33 of his professional fights - and significantly, all but one of the bouts have taken place in Germany. He's the current WBA and IBF super middleweight world champion. Fifteen of his 33 victories have come on points at the end of a 12-round contest, showing how important home advantage can be.
Many who follow boxing believe the judges who make points decisions are biased towards home fighters. However, judges in world title contests don't always come from the home country, so that's not the deciding factor.
It's worth noting that the fight promoter often pays the judges, and the promoter is often backing the home fighter. This is a clear conflict of interest that leads many to suspect some of the decisions that are made.
For that reason, you should always do as much research as possible on the judges when one of the boxers in a bout is fighting in his own country.

2. Date of birth 30 June 1966 (Brooklyn, US)
Weight: 15st 13lb
Height: 5ft 10in
Division: Heavyweight
Professional Record: 56 fights, 50 wins (43 knock-outs), four defeats, two no contests
Mike Tyson has won 52 of his 56 professional fights to date, with an incredible 30 of those victories coming in the first two rounds.
Throughout his 19-year career he has been a devastating early finisher. He claimed his first world title with the second-round knock-out of Trevor Berbick (in November 1986) and has scored numerousearly victories since.
Tyson may be a spent force now, but he remains the ultimate example of an early finisher who struggles in the later stages of bouts. The four defeats in his career have come in the tenth round (to James 'Buster' Douglas in 1990), the 11th round (to Evander Holyfield in 1996) and the eighth round (to Lennox Lewis in 2002). His other defeat was that infamous disqualification when he bit Holyfield's ear during a title bout in 1997. You'd have done well to get a bet on that.
