Even though Bolt did not win the 100m title he will remain the greatest track and field athlete of all time.
Twice for doping banned Justin Gatlin of the United States won the World championships 100m title as his teammate Christian Coleman took silver.
"I tightened up at the end and that is something you should never do. I didn't execute when it mattered.
"I am not fully comfortable in those blocks but you have to work with what you have. I can't complain about that.
"He [Gatlin] is a great competitor. You have to be at your best against him. I really appreciate competing against him and he is a good person." Bolt told BBC reporters.
Usain Bolt still has one more race left before he retires as he competes next week in the 4x100m relay.
