Anthony Joshua fights Wladimir Klitschko at Wembley Stadium on Saturday and looks to add the WBA heavyweight title to his IBF belt.
By contrast, the Ukrainian aims to become a three-time world heavyweight champion in his first return to the ring since losing his crown to Tyson Fury in November 2015.
Here, we take a statistical look at their career numbers up until this point.
Anthony Joshua
18 – Joshua has had only 18 professional fights, yet is the favourite to beat one of the finest heavyweight champions in history.
18 – he has stopped all 18 of his professional opponents inside the distance, giving him a 100 per cent knockout record.
3 – the number of world heavyweight title fights he has been involved in – against Charles Martin, Dominic Breazeale, and Eric Molina, all of America.
3 – the number of recognised professional titles Joshua has won. He is the reigning IBF heavyweight champion, and once held both the British and Commonwealth titles.
5 – five of Joshua’s 18 opponents were stopped inside a round. Emanuele Leo, Hector Alfredo Avila, Matt Legg, Michael Sprott and Gary Cornish were all unable to survive even three minutes with him.
7 – the highest number of rounds any of Joshua’s fights have lasted. First Dillian Whyte and then Breazeale proved his most resilient opponents.
7 – Joshua’s age in years when Klitschko made his professional debut, in November 1996 against Fabian Meza. The Briton was six when Klitschko won Olympic gold at Atlanta ’96.
1 – Olympic gold medals won. Joshua’s came at London 2012.
44 – the number of rounds he has boxed as a professional. Klitschko surpasses that in his five most recent fights alone.
90,000 – the number of spectators expected to attend Saturday’s fight, a post-war record for a boxing event in the UK.
Wladimir Klitschko
68 – Klitschko has had 68 professional fights, which is already over a third more than the fighter widely considered to have preceded him as the world’s leading heavyweight, Lennox Lewis.
78 – the percentage of opponents Klitschko has stopped inside the distance. He has won 64 of those 68 fights, and 53 via stoppage.
3 – the number of fights in which Klitschko has been knocked out. Only one of his four defeats – against Tyson Fury in November 2015 – came on points.
3 – Klitschko held three separate, recognised versions of the heavyweight title until that defeat: those from the WBA, WBO and IBF. He has never simultaneously held all four
358 – the total rounds the Ukrainian has boxed as a professional, which gives him 314 more than the inexperienced Joshua.
18,240,000 – the value, in pounds, of the winning purse bid for Klitschko’s fight with Alexander Povetkin, which was held on 5 October 2013, the same night Joshua made his professional debut.
18 – Klitschko has made 18 successful defences of a world heavyweight title. He remains seven shy of the all-time record held by Joe Louis.
1 – the number of Olympic gold medals won. Klitschko took his at Atlanta in 1996.
8 – eight of Klitschko’s fights have gone the 12-round distance. Joshua, in contrast, has never fought beyond the seventh round.
