Yusuf was caught collecting money from investigative journalists posing as football agents who wanted their players picked for the 2018 African Nations Championships (CHAN).
Rohr insists that his assistant Salisu is an honest man who was a victim in the case.
"I saw the video, and I saw what happened," Rohr told KweséESPN.
"From my experience, Salisu is an honest man."Those people just want to make trouble, this is people just trying to catch some people.
"Salisu does not need that money, he is a victim of this situation."
The Nigeria Football Federation (NFF) are currently investigating the case and Yusufwill appear before the body’s Ethics Committee when he returns from a trip to the United Kingdom.
In an investigation led by Ghanaian journalist Anas Aremeyaw, reporters posing as football agents for some players approached Yusuf in September 2017 for a conversation about players’ selection.
