And Bolt relished the adulation at the 60,000-capacity Olympic Stadium. Bolt said: 'There are no words to describe how I am feeling.
For the better part of the past decade, Bolt has been 100 percent reliable in getting relay gold for the island nation.
Gatlin was booed every time he was introduced to the crowd at the London Stadium at the weekend, with spectators also jeering once it was clear that the 2004 Olympic champion had won 100m gold and ruined the retiring Bolt's farewell.

"It probably would've been even worse", Bolt said.
Those quicksilver feet which always dealt in gold have another chance to obey his command as he seeks to bring down the curtain on his matchless sprint career and land a 20th global championship title in the 4 x 100 metres relay. We can only agree with her assessment that "I cannot ask for anything more".
