Heavyweight legend 'Iron Mike' enjoyed a stellar boxing career, having achieved it all at professional level before retiring in 2005, having reigned as undisputed world champion from 1987 to 1990.

And his credentials were certainly proven at amateur level, where he won a gold medal at the 1981 Junior Olympics in the heavyweight division.

In the final, the heavy-handed American made a statement like no other with the landmark event lasting just eight seconds against rival Joe Cortez.

Tyson quickly burst out from his corner with just one intention, and began loading up some vicious shots.

But after just eight seconds with Cortez clearly way out of his depth, the 15-year-old at the time landed a crushing right-left combination which sent his opponent crumpling to the canvas.
