De Santis, who has been with the Impact since 1993 and has held the role of sporting director since 2011, will remain at the club but only in an administrative role and will no longer be involved in any technical decisions.
"In business, the most difficult decisions to make are those made involving emotions," Saputo said. "This is why, today, I am forced to make this decision with a heavy heart. After twenty years of being part of the technical team as a player, successful coach and GM, it gives me great sadness to announce that Nick De Santis has been relieved from his functions."
Saputo stated that Frank Klopas will stay on as head coach and director of player personnel for the remainder of the current season, as well as for the 2015 season. Klopas will be given full control over all technical matters, while the Impact consider a potential restructuring of the club.
The Impact are having their worst season in MLS since they joined the league in 2012. They are last place with 14 points from 20 games.
