Muhammad Ali can’t remember his last world title, daughter reveals - PHOTO+VIDEO

Ali, who has been fighting bravely against Parkinson's Disease for 30 years, has no memory of his third world title victory against Leon Spinks in 1978, often telling his daughter Hana that he plans on becoming a three-time champion.But the sporting legend still has his wicked sense of humour, Hana says, and after being corrected on his great achievements jokes that he could yet make a comeback aged 72.Speaking to The Sun, Hana said: 'A few months ago he was messing with me and telling me he was going to become the three-time champ.'I said, "You're already the three-time champ. If you come back you'll be the four-time champ". He said, "No, no - I'm the two-time champ."'He said, "I'm going to look it up." And then he calls me back and says, "I'm the three-time champ, so I'm going to be the four-time champ."'Ali, then fighting under his birth name Cassius Clay, won his first heavyweight world title in 1964 as a 7-1 underdog when he defeated Sonny Liston.He held the belt until 1967, by which time he had converted to Islam and named himself Muhammad Ali, when he was stripped of the title for refusing to fight in Vietnam.He made a comeback and in 1974 knocked out George Foreman in the eight round of the Rumble in the Jungle to become world champion for the second time. He held the title for four years before unexpectedly losing to Leon Spinks in 1978, but defeated him in Las Vegas months later - the bout he does not remember.  Hana, 38, and half-sister Maryum, 46, denied rumours that their father is unable to speak, bedridden and close to death.They added that despite Ali's Parkinson's, which can cause tremors, slow movement, problems with speech and memory loss, his fighting spirit remains the same. 'His personality has not changed. Time changes his body, his physicality - but his spirit doesn't change.'A new documentary, called I Am Ali, opens in cinemas tomorrow and is based on 80 hours of tapes of unheard conversations between him and loved ones during the latter stages of his career.In one, Maryum, then 11, can be heard begging not to fight again.Despite Ali being diagnosed with Parkinson's in 1984, his daughters say he was already showing signs of the disease in 1979 - the year he retired.'That was a very stressful time for us. A lot of people wanted him to stop fighting,' Maryum said.Hana added: 'It was hard listening to it, knowing what was to come.'  Bakudaily.Az
