Boxing legend Cassius Clay aka Muhammad Ali passed away on Saturday aged 74 after battling a respiratory illness.

Widely acknowledged as one of the finest individual sporting champions of all time, Ali proclaimed in February 1964 just before his world title fight against Sonny Liston that he is the ‘greatest ever’.

In the video, Ali says, “Fifteen times I have told the clown ......, he was going down and this can be no different. He will fall at eight to prove that I am great and if he keeps talking gaff, I am going to cut it to faff.”

Ali went on to beat Liston in the fight held at Miami, Florida on February 25, 1964.
