Go back 39 years, to when an ageing but still brilliant (in and out of the ring) Muhammad Ali fought Leon Spinks is a return bout, and the word record was set for biggest indoor attendance for a boxing match.
Ali-Spinks II, the fight that saw “The Greatest” make history as the only man to have won the world heavyweight crown three times, took place at The Superdome in New Orleans and an incredible 63,315 fans paid to attend. But next month’s Anthony Joshua-Kubrat Pulev fight is on target to smash that record.
