Former 200m world record holder and Olympic champion, Michael Johnson, said after the semi-finals.
"Gatlin was impressive again and showed why he is the fastest in the world this year.
"It was another high-quality race, with flawless execution of the bend and the transition so he could show his power.
"Usain looked relaxed and ran within himself. He got out of the blocks well but wasn't great around the bend.
"He looked a bit tired in the straight, because of the lack of training he has been able to put in. But he is still in very good shape, just not the type of form we are used to seeing from him.
"He was very honest afterwards, in that he doesn't really know where he is at. He is not really at his best compared to years past, so it is difficult to judge. It was far below par for Bolt."
