Ghana's coach Milovan Rajevac hailed his heroic Black Stars and blamed a "sporting injustice" for their agonising exit from the World Cup at the hands of Uruguay.
A handball on the goal-line by Luis Suarez prevented Ghana's Dominic Adiyiah from scoring the winning goal in the last minute of extra time and Asamoah Gyan missed the penalty - with Uruguay triumphing in the shoot-out that followed.
Rajevac said: "There are no words to express what we feel. This is sport's injustice but I congratulate Uruguay - they were the lucky ones."
He added: "All I can say is that this is football. At the end we had an historic opportunity to reach the semi-final - we had a penalty but you saw it all.
"The opponents had the psychological advantage in the shoot-out. Everything happened so fast.
"We really had big support and it would have been a fairytale if it ended well for us, but I would like to congratulate Uruguay on reaching the semi-finals."
Uruguay coach Oscar Tabarez said it was "too harsh" to say that Suarez had cheated and that the Ajax striker had reacted instinctively.
Tabarez said: "When there is a handball in the penalty area there is a red card and the player is thrown out of the game.
"Saying we cheated Ghana is too harsh a word to use. We also abide by what the referee did - it could have been a mistake. Yes he stuck his hand out but it's not cheating - I don't think it's fair to say that.
"I think it was instinctive. The player instinctively reacted and was thrown out of the match and he can't play the next match. What else do you want? Is Suarez also to blame for Ghana missing the penalty? We try to be dignified and if we lose a match we look for the reasons for it. You shouldn't look to third parties."
