Reinhard Rauball told Germany's Welt Online that Blatter should step down as soon as possible so that FIFA can make a fresh start.
Blatter has acknowledged he knew about payments by marketing agency ISL to former FIFA chief Joao Havelange but insisted they were legal in Switzerland in the 1990s.
Blatter insists "it is difficult to measure the past by today's standards."
"Bribery is unacceptable and I neither tolerate nor seek to justify bribery, but this is what I am now accused of," Blatter told Sunday's editions of Swiss paper Sonntagsblick in comments provided by FIFA.

"Now it is on record what I have always said: I have never taken nor received any bribes ... the people who attack me now know this is the case but still they persist. They want me out."
Rauball also called for an extraordinary FIFA congress where the members of football's governing body should strip Havelange of his honorary presidency.
