"I had a feeling that the referee had one set of rules for us and the other for Brazil. I don't want to talk about referees but everybody saw how he did his job. He didn't have respect for Croatia. He's not good enough to be a referee in such a important game," Xinhua quoted Kovac as saying in an interview to Croatian Television after the match.
During the match Kovac had a poker face. He held it until 70th minute when Nishimura pointed to penalty spot after Dejan Lovren challenged Fred in Croatia's penalty box.
"If that was a penalty than we don't have to play football anymore. This is not basketball. This was a robbery," the Croat coach said.
Croatia players and other experts shared his opinion.
"We should be talking about great game, two great teams fighting and instead we have to talk about the referee. It's a shame that one person can destroy everything that we worked for. I think we deserved more," Croat midfielder Ivan Rakitic said.
For all Croats this was the greatest match in the young country's history. For Brazilians this was just the first of the seven steps on the way to the sixth World Cup trophy. In the 11th minute it was Croats who were in seventh haven when Marcelo accidentally pushed the ball into his own goal after cross from Ivica Olic.
"In the first 20 minutes Croatia played like you should play against Brazil. They were focused, the midfield was covered and when they got the ball they were fast and dangerous. On one such occasion they got the goal," said Goran Vlaovic, former player from Croatia's Golden Generation.
But there was still 70 minutes to play and Brazilians were getting closer to Croatian penalty box by each minute. Croatia goalkeeper Stipe Pletikosa had some great saves but he couldn't stop Neymar from scoring in the 29th minute.
Pletikosa was close to stop Barcelona's star penalty kick in the 71st minute but the ball went of his hands into the net. In the stoppage time Oscar confirmed Brazil's victory with clever shot when he was few meters outside the penalty box.
"It's not easy to play against the team that has so many great individuals. Just because of that they can be dangerous even without paying attention to tactics. Croatian players did a great job. There is not much more they could do. They even had a chance to make it 2-2 at the end of the match but that didn't happen," Robert Prosinecki said.
Vlaovic, Prosinecki's former teammate from the 1998 World Cup squad, was a bit more critical of Croatia's presentation in Sao Paulo.
"After great first 20 to 25 minutes Croatia didn't do enough. It seemed that they didn't have a will to attack Brazilians. They became slower and if you play slow against Brazil than you are in danger because they have fast players. Every time when Croats lost the possession Brazilians were dangerous," Vlaovic said.
When he wasn't talking about the Japanese referee, Niko Kovac was full of praise for his team. "We were not just good. We were excellent in both halves. This is how you fight for your team and I am very proud of my players. They did everything that we've planned. It's a shame that we didn't have a lead after the first half. If we continue to play like this I am convinced that this team will advance to the knockout phase."
