Argentina's refereeing body has accused Steve Clarke of being 'rude' for his criticism of their whistler Facundo Tello after his refusal to award Scotland a penalty against Hungary.
The Scotland boss was raging at Tello's decision not to award a spot kick when Stuart Armstrong was preparing to shoot and afterwards questioned why an Argentinian ref was in charge at the European Championships.
But Tello has won praise in his own country from the Institute of Argentina Refereeing's director, Miguel Scime - an ex-FIFA referee who now advises the world football's governing body.
And he wasn't impressed at Clarke's outburst.
He said: "That was a very good job by Facundo Tello and his team of assistants, Gabriel Chade and Ezequiel Brailovsky for the match between Scotland and Hungary.
"I was sorry Scotland tried to justify their failure to qualify with the comments the coach made.
"It wasn't a penalty and his comments after the game were just rude. No one has the right to criticise the refereeing team in that way."
Clarke faces a sweat before seeing if UEFA take any action on his outburst where he bitterly complained about Tello's performance and nationality.
The Scotland manager had said: "The moment in the game is the penalty. It is 100 per cent a penalty.
"Somebody has to explain to me why that is not a penalty because otherwise, I'm thinking there is something wrong.
"What is the point [in speaking with the referee]? He is from Argentina. What is the point? Why is it not a European referee?
"I don't understand why he is here and not in his own country refereeing the game.
"I don't understand the VAR can look at that and say it is not a penalty, just my opinion."
