One man who may be set to spoil Bolt's farewell party is 
Canadian athlete Andre De Grasse.

 London with the aim to win. 
The event is being billed as one of the biggest sporting spectacles 
of 2017, not least because the legendary Bolt will be bidding 
an emotional farewell.
The championships start on Friday, August 4, running through
 until Sunday, August 13 - with the men's 100m final set to
 take place on Saturday, August 5.
