Michael Johnson, the double track gold medallist at the 1996 Olympics, is sceptical about Usain Bolt's bid to win four gold medals at next year's London Olympics, which would equal Carl Lewis's feat at the 1984 Los Angeles Games.
Bolt has announced his plans to enter the sprint double and the two relays.
But Johnson believes the metres relay would be a distraction, as it's a difficult distance to train for, and he'd have to prove himself to the Jamaican coaching staff.
