To go at the top is always positive. I believe he gave everything to the national team and that now is the time to give way to another person," Eugenio Lopez told FM Delta.
Argentina are one match away from winning their first World Cup since 1986, but they face a Germany side who are on top form after hammering hosts Brazil 7-1 in their semi-final.
Argentina's state news agency, Telam, said the 59-year-old Sabella's contract was due to expire after the tournament. He took control of the national side in 2011.
"He's going. He's leaving whatever happens. Whether they are champions or not, a cycle is ending," Lopez added.
