Ghana coach Ratomir Dujkovic said it "hurt" to have been sent off during the World Cup defeat to Brazil - and accused the referee of bias.
Dujkovic was banished from the dug-out at half-time after confronting Slovakian referee Michel Lubos.
"I told him it would be better if he put a yellow jersey (Brazil colours) on," Dujkovic said after the 3-0 loss.
"I have never been sent off in my life and it hurts. But I suppose there has to be a first time for everything."
Brazil coach Carlos Alberto Parreira had little sympathy for his counterpart, however, saying: "That is what losers do, they whinge and they cry."
Dujkovic was still bursting with pride, though, at his team's achievement in becoming the only African side to reach the last 16 in Germany.
"They faced a great team, the world champions, who are the best in the competition," said Dujkovic.
"It is not a shame to lose to Brazil. I said before that Brazil were favoured to be champions, the world champions."
Dujkovic was sent to the stands at half-time after Adriano had doubled Brazil's lead when he was clearly offside.
Earlier, Ronaldo opened the scoring after just five minutes while Jose Ze Roberto wrapped things up shortly before the final whistle.
However, Ghana out-played Brazil in the first half and could have caused an upset were it not for some profligate finishing.
