not everybody loved Grobler.
British rower Josh Bugajski was scathing in his appraisal of his former coach.
"I will admit he is a good coach to some people," said Bugajski. "But there were people that he seemed to take a disliking to.
"I am going to be brave and say something the crew don't want me to say - I popped a bottle of champagne when Jurgen retired.
"I had three very dark years under him. I would be a coward not to say on behalf of the guys who are back home and didn't make it on to the team and got the darker side of Jurgen."
