David Gallop was the man that broke the news and attempted to explain the situation last week - which only sparked further debate.
With rumours swirling that Stajcic was targetted and unfairly sacked, Nikou has finally weighed in declaring the right decision was made based on the 'plain, boring facts of the situation'.
"I know there's a lot of opinions out there in the marketplace at the moment because in sports it's a very emotional space - football's probably the most emotive," Nikou told ABC's The Ticket.
"But at the end of the day we had a very detailed board discussion on the evidence before us.
"It was a unanimous decision...this was the right decision for this playing group at this point in time - both for now and the future.
"Unfortunately those sorts of rumours and innuendo are much more interesting than the plain, boring facts of the situation. We dealt with the issues as they were presented to us without any of those motives people have tried to put to us."
Though the rumblings around Stajcic's sacking are unlikely to stop anytime soon, the FFA remain focused on appointing a swift replacement with plenty of candidates stepping forward.
"We've been swamped by applications for this role, it remains a great role to be involved with a wonderful playing squad, it's got a lot of upsides," Nikou said.
"I think people in the football community can rest assured that the most qualified person — and the person best placed to take this group forward — will be appointed, whether that be male or female."
Time is of the essence for the Matildas, who host the inaugral Cup of Nations in late February before competing in the Women's World Cup in June.
