Michael Johnson, United States’ four-time Olympic gold medallist:
“I expected a little faster but the race is what it is. Usain Bolt was straight into the lead and never relinquished it. This was a quality race.
“You could not separate the guys for bronze. I don’t think Adam Gemili could have done more to get that bronze.
“If you look at his race and his position, he finished ahead of guys like [former Olympic and world 400m champion] LaShawn Merritt.”
Colin Jackson, Great Britain’s two-time world 110m hurdles champion:
“Usain Bolt was so aggressive out of the blocks. Andre de Grasse said he wanted to go with Usain and that is what he has done. If I am honest, many of the athletes will be disappointed with their times.
“My heart goes out to Adam Gemili. To be fourth with the exact same time as third place, Adam will be devastated no doubt but he is still fourth in the world, he has to remember that and he has a bright, bright future ahead of him.”
