Brawn, however, believes Barrichello's comment scame in the heat of the moment and said the Brazilian had moved on already.
"I think that is a frustrated racing driver," said Brawn. "When you put so much into a race and it hasn't worked out, then that is what you get sometimes.
"If you get out of the car thinking you should have won the race and you haven't got all the facts, then that can happen. Now he has the facts and understands what happens, he is fine."
The team boss also reckons Barrichello will understand he just wasn't fast enough to win the race.
"It's a passion some drivers have," he added. "But I want to have a look at exactly what he said and be clear, but he understands now what happened in the race. Rubens had the 11th fastest time in the race today.
"You cannot win a race, whatever strategy you have, if your best lap is only 11th quickest. It is just not possible. Those are the facts.
