(Reuters) Blatter, under fire over allegations of financial mismanagement and bribery relating to his election as president, is facing a fight to retain his position against the head of African football, Cameroon's Issa Hayatou.
"For me, he [Blatter] is the favourite against Hayatou," Beckenbauer told the German press.
The battle for the FIFA presidency will be decided at the organisations's congress on May 28-29 in Seoul.
Beckenbauer, the Bayern Munich president who also chairs the organising committee of the 2006 World Cup finals in Germany, said he doubted there had been any irregularities when Blatter was elected president in 1998 in Paris.
The former World Cup-winning captain and coach also said he believed Blatter had done nothing wrong in relation to last year's financial collapse of FIFA's marketing partner ISL-ISMM.
"After four years, two Somalis are now saying that they were bribed for the Blatter vote," Beckenbauer said. "Why didn't they say anything before?
"And the collapse of ISL is not Blatter's fault."
The 56-year-old also dismissed suggestions that he would run for the FIFA job himself in 2006.
"At the moment I would say no," he said. "If the 2006 World Cup is a success and once it's behind us, I just want to go mountain climbing and play golf."
Franz Beckenbauer has offered his support to FIFA president Sepp Blatter and believes he will remain leader of soccer's world governing body.
