Usain Bolt has blamed his dodgy starts for his shock 100m defeat to Justin Gatlin.
Jamaican superstar Bolt waved farewell to individual athletics without the fairy tale victory as American Gatlin romped home at the London Stadium.
The eight-time Olympic champion eventually came third as Christian Coleman also pipped him to silver.
Usain Bolt complained about the starting blocks at the World Championships after his heat victory on Friday night.
And Bolt, who will say goodbye to the sport after the 4x100m relay next Saturday, refused to lay liability at the blocks and instead held himself responsible for his frustrating exit.
Bolt told the BBC: “The start is killing me. Normally I get better though the rounds.
“It felt like it was there but the reason I lost was because I couldn’t get it. You have to transition.
