Bolt, a life-long United fan, has long expressed the belief that after he retires from athletics he would be good enough to play top flight football.
But the 29-year-old sprinter is an outspoken critic of the current Old Trafford boss, and played down his chances of joining while Van Gaal is in charge.
'I supported Manchester United for years,' said the six-time Olympic gold medalist.
'I would still love to play for them, but if Louis Van Gaal is the coach, not so much.'

The comments follow Bolt's criticism of Van Gaal on Norwegian TV last week, when he claimed the players are not committed to their manager.

It has been up and down,' admitted Bolt. 'I wouldn't say I'm happy. I think a lot of players don't want to come to the team under Van Gaal. I think players don't want to play for him.
'He plays a different style of football which Manchester United doesn't really play. We are more of an attacking team and he likes to pass the ball.
'I'm not saying he's not a good coach but, personally, I just think he's not right for Manchester United.
