Vitali Klitschko (44): The giant Ukranian was virtually unbeatable as a prizefighter. It’s a shame hardly anyone really noticed. ‘Dr Ironfist’ was well renowned for his awkward style, granite chin and long reach. Those attributes put him in a physical class few heavyweights have ever achieved, and his 87.23 per cent knockout ratio, No2 all time behind Rocky Marciano’s 87.76 per cent, will remain among the highest in the division’s history for years to come. He finished his career with only two losses and is now Mayor of Kiev.

LaMarcus Aldridge (30): Centre for the San Antonio Spurs having left Portland Trail Blazers this summer.

Gregory Vignal (34): Former Liverpool and Portsmouth leftback who now plays for CFA club AS Beziers. 

Jon Jones (28): Former UFC Light Heavyweight champion and widely considered one of the best ever.
