Despite the significant backlash, Ben Sulayem has claimed that he would consider reinstating Masi if a suitable opportunity arose.
"I always apologise, but I cannot apologise for something which was done before my time," Ben Sulayem told PA.
"OK, I will do the apology, but I will bring Michael Masi again. Do you think that is right? The poor guy is a person who has been attacked and abused.
"Michael Masi went through hell. Hell! And if I see there is an opportunity that the FIA needs, and Michael Masi is the right person, I will bring him.
"I even had people threatening me to kill me because I had the power to change it. But I said to them: 'Sorry, the World Cup of 1966, England against Germany, was that correct? Did they change it? No.' Did they give it to Germany? Nein."
