Scotland fans and the Scottish Football Association have refuted claims Brazil star Neymar was racially abused by the Tartan Army in Sunday's friendly at the Emirates Stadium.
A banana was thrown onto the field during Brazil's 2-0 victory over the Scots, while Neymar accused some spectators of racist behaviour - a claim repeated by team-mate Lucas Leiva, who retrieved the banana.
It is unclear whether it was thrown by a supporter of either side or by a neutral and an SFA spokesperson told Press Association Sport: "There has been no such incident reported to the police or the stadium safety officer. In fact, the tens of thousands of Scotland supporters who travelled to the Emirates were commended for their behaviour."
The spokesperson added: "The Scotland supporters are known the world over for their impeccable behaviour and we have no reason to believe that, after speaking to the relevant authorities, they have been anything other than exemplary.
"The Scotland fans helped create a wonderful spectacle inside the Emirates and throughout London and should be applauded for their support."
Neymar, who scored both goals on Sunday, was jeered by some spectators after receiving treatment in the first half following a Scott Brown challenge.
Tartan Army spokesman Hamish Husband strongly denied the catcalls were racially motivated.
He said: "The reason Neymar was booed was because we believed he was feigning injury.
"Racism has no place in the Tartan Army and if it did, it would be stamped out immediately because we are self-policing.
"Any suggestion of racism from the Tartan Army, as far as I am concerned, is absolute tosh. We accept that Brazil played us off the park, and we applauded them for that."
