Scottish Football Association chief executive Stewart Regan has contacted the Brazilian federation to ask for an apology over Neymar's claims of racism after Sunday's friendly at the Emirates Stadium.
Neymar, who scored both goals in his side's 2-0 win, complained afterwards that he had been the victim of racist abuse, an allegation strenuously denied by the SFA and the Tartan Army fans' organisation.
A subsequent investigation by Arsenal and the Metropolitan Police concluded that a banana was thrown onto the pitch by a German student sitting in the area of the stadium reserved for Brazilian supporters, and that no Scotland supporters were involved.
Regan remains unhappy that the reputation of Scotland fans has been called into question, and has written a letter requesting the Brazilians, or Neymar himself, say sorry.
"It is very disappointing that this episode threatened to overshadow an entertaining match, played amidst a real carnival atmosphere created by supporters of both teams," said Regan.
"Scotland and Brazil have played many times over the years, each time in a colourful and friendly environment, and we feel that it's necessary to draw a line under Sunday's events.
"Scotland's supporters were genuinely upset and annoyed that the unfounded allegations levelled against them threatened to sully their reputation as fair, good-humoured and respectful spectators.
"As the matter has been resolved, and Scotland supporters cleared of any involvement, we felt it was only right that we acted on behalf of our supporters to request an apology either from the player involved, or the Brazilian FA."
