Salman, expected to be able to call upon the bulk of support among the 47 members in the Asian confederation, said he was the man to fix FIFA, which has been reeling since May when the United States indicted several FIFA officials for bribery, money laundering and wire fraud.
Swiss authorities are also investigating the decision to award the 2018 and 2022 World Cups to Russia and Qatar.
"With the support I'm going to get, we're going to turn it around very quick," Salman said.
