The 2005 US Open golf champion Michael Campbell believes he still has at least another five years in top flight golf and says he's yet to achieve all his ambitions.
Campbell has been recovering from a shoulder injury for the last three months and question marks have been raised over his longevity in the sport.
However he says he's still passionate about the game and still has plenty of golf left in him yet.
