Sprinting great Michael Johnson has suggested that any ill-feeling that lingers towards Justin Gatlin is down to a lack of "contrition" shown by the sprinter.
Gatlin has been widely criticised during the ongoing World Athletics Championships, having come back from two doping bans to challenge Usain Bolt for sprinting supremacy.
His agent has slammed the treatment of his client, but Johnson believes that the lack of an apology from Gatlin is part of the problem.
"Justin hasn't given any apology, shown contrition or tried to understand why people feel the way they do about him," Johnson told BBC Sport.
"The excuse he gave for his second positive test is hard for anyone to buy - he has to understand that, and then he might understand how we feel.
"We have also been talking about how fast he has been running all week and how incredible his form and technique is, but we have to talk about all of what's going on."
Gatlin, who saw a 28-race unbeaten streak come to an end at the hands of Bolt in the 100m on Sunday, will go up against the nine-time world champion again this afternoon in the 200m final.
