le Roux's comments did not relate to all the players, but he said: "Some players are simply not mature and responsible enough". He recently left his role with the team, saying he wanted to spend more time with his family in Bloemfontein, but it is believed he became increasingly frustrated when the players wouldn't heed his advice.

"I felt confident (before the tournament) that, apart from Roger Telemachus, all players in the squad were physically ready for the challenge of a two-month tournament," wrote le Roux in the report. "In my opinion the use of alcohol within the national team is a problem. This ... does not include all the players, but it does include players who play a vital role within the team."

However, the South African board has been quick to respond. "CSA denies media reports that Adrian le Roux resigned as physical trainer because of alcohol abuse among some of the (team).

"He stated clearly in his letter of resignation that he was leaving cricket to concentrate on a new career so that he could be with his family in Bloemfontein. We reluctantly accepted Adrian's resignation because he was a highly valued member of the management team. However, we respected his reasons for leaving because he wanted to stop travelling and be with his family."

It went onto say that concerns raised after the World Cup have been dealt with. "CSA did hold an official inquiry following the match against New Zealand at the World Cup, and it was found that a number of players had been drinking into the early hours after the match.

"We viewed this in a serious light despite there being no curfew in place on an off day. We have now changed the curfew and other regulations regarding alcohol intake while on tour.

"The inquiry, our findings and recommendations took place well before Adrian submitted his routine report after the World Cup. It is a matter of grave concern, however, that a confidential report with limited distribution to CSA officials should be leaked and sensationalised in this way."

Coach Mickey Arthur added: "The regulations about the intake of alcohol on tour was only one aspect of a generally very positive report on the fitness levels of the team from Adrian," he said. "We addressed all matters including this that arose regularly on tour and took steps accordingly.

le Roux also made it clear his report was not meant for public consumption. "I was employed by CSA as the fitness trainer. In this professional capacity part of my duties is to submit regular reports on all aspects of physical conditioning."

"This was no different after the World Cup. A routine report was sent in confidentiality to individuals within CSA and it is disappointing that it is now public knowledge."
