Speculation was rife after Bayern's 4-2 German Super Cup final defeat by Borussia Dortmund that Guardiola was in the market for another centre-back, with Luiz's name top of his list.
But Guardiola, speaking at a presentation before the Audi Cup in Munich, said he was happy with his defensive options.
Bayern have the option of dropping holding midfielder Javi Martinez back now that Thiago Alcantara has arrived to fill a similar role to the one he had last season.
"He's not coming to Munich," he said. "We've got four or five central defenders.
"There is no truth to the speculation."
