The Scottish FA is writing to UEFA for clarification over Scott McTominay's disallowed goal in Thursday night's 2-0 loss in Spain.
The Manchester United midfielder looked to have put Scotland ahead in the second half, however, following a VAR check his free-kick was ruled out by Dutch referee Serdar Gözübüyük.
It appeared the goal was initially disallowed for a foul by Jack Hendry on goalkeeper Unai Simon but was then attributed to offside - with the Scotland defender deemed to be interfering with play and impacting Simon's ability to save the shot.
Sky Sports News understands the SFA wants clarity on the decision-making process and chronology of seemingly conflicting events.
However, a UEFA source confirmed to Sky Sports News on Friday that McTominay's strike was chalked off for offside against Hendry by referee Gözübüyük.
