PARIS,  (Reuters) – Usain Bolt knows he has been short  of his very best form since returning from injury and is keen to  be more like his true self when running the 200 metres at the  Paris Diamond League meeting tomorrow.

The Jamaican faces Frenchman Christophe Lemaitre at the  Stade de France aiming to run 19.75 seconds, still well short of  his world record 19.19, as he prepares for the defence of his  100 and 200m titles at the Daegu world championships from Aug.  27-Sept.4.

A back injury forced him to cut short his 2010 season and he  has since been feeling his way back, although major rival Tyson  Gay will miss out on the upcoming worlds through injury.

“I can’t get complacent because Tyson Gay has dropped out.  I’m working hard, I’m working back from injury so my focus is  trying to get back to the Usain Bolt everybody knows and loves  and for me, my goal is just to defend my title,” Bolt told  reporters.      “I’ve said that I want to become a legend in the sport and I  think if I defend both my titles back to back it will make me  one. Only a few have done that so for me, that’s my aim, that’s  my goal this season.”

Other top names in action in the French capital tomorrow  include women’s 800m world champion Caster Semenya and Cuban  110m hurdles Olympic champion Dayron Robles.
