Amid final political attacks and pleas, Sheikh Salman, Infantino and their rivals went to regional confederation meetings in Zurich today ahead of tomorrow's vote to find a replacement for Sepp Blatter.
Football's multi-billion dollar world governing body has been in turmoil since the arrest of seven football officials in Zurich at a Congress in May over more than $200 million (182 million euros) paid in bribes. Others have been arrested and Blatter has since been suspended for six years.
Infantino called the Congress "a crossroads moment for FIFA" and said the decisions taken "will shape football for generations to come".
"FIFA needs to turn the page on the controversies," said French contender Jerome Champagne, a former FIFA official.
