Olympic champion Darren Campbell has hit out at American sprinter Justin Gatlin following his victory over Usain Bolt in the Diamond League 100m in Rome.
The 31-year-old secured a surprise win over the fastest man in the world by finishing the race by one hundredth of a second ahead of the Jamaican with a time of 9.94 seconds.
Gatlin has served two suspensions due to doping offences - one two-year ban in 2001 and another for four years following a failed drugs test in 2006.
"It is very uncomfortable when you think Justin Gatlin hasn't been caught for drugs once, he's actually been caught for drugs twice and here he is beating the great Usain Bolt," Campbell told BBC Radio Five Live. "If it had been an athlete who hadn't been done for taking drugs, there would have been a lot more noise about it this morning."
Bolt was competing for the first time since recovering from a hamstring injury, which he suffered last month.
