Indiscipline and not doping, was the reason two Mexican players were expelled from the Confederations Cup, Franz Beckenbauer has confirmed.

Salvador Carmona and Aaron Galindo were thrown out of the competition by Mexico coach Ricardo Lavolpe on Tuesday, amid rumours that they had tested positive for nandrolone.

But Beckenbauer said he had been told by FIFA president Sepp Blatter that drug taking had nothing to do with the scandal.

“He (Blatter) assured me that this was purely a disciplinary matter and nothing to do with doping.

“And we’ve got no reason to question it.”

Quizzed about the doping allegations, Lavolpe said: “The journalists should be concerned with judging the sporting quality of our team. Everything else is only a matter for us.

“I don’t ask you whether you’ve got marital problems at home?” he told a press conference.

FIFA spokesman Markus Siegler dismissed speculation.

“We heard a rumour, and I stress the word ‘rumour’, that the Mexican players Aaron Galindo and Salvador Carmina had tested positive,” he said.

“Mexico played two World Cup qualification matches on June 4 and June 8 and there is no information about a positive doping test,” he said.

“We’re waiting for their response during the day,” Siegler said.
