Mohammed Ali was a lovely boxer, blessed with exceptional skill, speed and resilience. I was a big, big fan. I remember, as a young lad, rising in the middle of the night to listen to his totally unexpected demolition of Sonny Liston on the radio in the middle of the night, when he first became a world star. He was probably the best boxer of my lifetime. But I've never thought that Ali (or Clay as he was when he beat Liston) was the greatest sportsman ever. But this raises the question about who the greatest is. Personally, I think Usain Bolt has a very good claim.
When I search back through my sporting memories, I cannot recall any other occasion when I have been as amazed by sporting performance. Today, the Telegraph seems to be suggesting that Kenensia Bekele is Bolt's equivalent. I've heard others suggest that Tiger Woods and Roger Federer may be. All these are wonderful sportsmen. But for me, the greatest is Usain Bolt.
