Usain Bolt ... NOOOOOOOOOOO!!!!!!!!!!!!!!!!!!

The greatest sprinter in the history of man joined the guys at French soccer club JS St-Jean Beaulieu for a workout ... and got two pretty wide open shots on goal -- and blew 'em both. 

It wouldn't be a big deal if Usain was just a casual footballer ... but he's said he wants to focus on a soccer career after he retires from track in 2017. 

Dude, gotta make those shots.
