Former world 100m champion Kim Collins believes it's time to "forgive" drugs cheat Justin Gatlin. Collins says "murderers come out of prison and are put back into society" so he wonders why Gatlin is still getting a hard time. Collins says it's "unfair" to keep talking about the American's doping past.

Collins also looks ahead to the 2015 World Championships in Beijing and says "the shot put is more interesting than the men's 100m". he says the top sprinters are killing the sport because they constantly "duck and hide" from each other.

He spoke to Sportsworld's athletics reporter Ade Adedoyin.
