The call was initially communicated on-screen in the stadium as a foul by Jack Hendry on goalkeeper Unai Simon.

But Uefa stated it was for offside.

Hendry - who was in an offside position - was deemed to have been interfering with play by making contact with Simon.

Spain went on to win the Euro 2024 qualifier 2-0 in Seville.

"We've asked for clarity, we've not asked for the audio," Mulraney told BBC Scotland's Sportsound programme.

"We've asked for clarity and an understanding of what the process was. We've got a responsibility to our fans and the nation. We need to represent our nation properly.

"It's not just Scotland who have been questioning this. I've had messages from all over Europe asking: 'what happened?'

"My answer is, I don't know. Transparency is very important and that's what we've asked for. I'm sure Uefa will be forthcoming with an explanation, which we can then give out."

Scotland players and head coach Steve Clarke were all left confused, with midfielder John McGinn stating post-match that the referee had initially communicated to them the goal had been ruled out for a foul.

Mulraney believes it will become common for VAR audio to be released in football, but that point has not yet arrived.

"Part of the reason we've not asked for it is we didn't think we would get it," the SFA president added.

"We want to understand what the decision was, why it was given and what was the process."
