Herrera sets his sights on beating Brazil after Cameroon triumph
JUN 14, 2014 6:49a ET
Oribe Peralta struck the only goal just after the hour as Mexico triumphed 1-0 in heavy rain at the Arena das Dunas in Natal.
It was the very least the Mexicans deserved for an enterprising display in which Giovani dos Santos controversially had two first-half goals ruled out for offside.
Mexico face their biggest challenge next as they travel to Fortaleza to face the hosts in their second Group A game next Tuesday.
Herrera told media after the match: "The team did great work.
"We need to work, now we are at the top with three points. We will go out to win the next game, we are more excited than ever.
"We will concentrate on what we have to do."
Herrera was pleased with the way his side dealt with their two early setbacks, when former Tottenham forward Giovani was twice, incorrectly, denied by a flag.
He said: "They disallowed two goals that were valid, but we knew it could be like that.
"The important thing is that we picked ourselves up, we looked for the result and we got it."
Cameroon, who have won just one match at the World Cup finals since 1990, were underwhelming after a week of turmoil following a row between players and the national federation over bonuses.
Coach Volker Finke, however, remains optimistic.
The German said: "We're very disappointed with the result - I think we deserved a draw.
"There's still all to play for, though, and we're going to head into the Croatia match with the intention of winning."
Goalkeeper Guillermo Ochoa also feels Mexico are ready for the challenge of hosts Brazil.
It is a formidable task but Ochoa is full of confidence.
The 28-year-old told FIFA.com: "We're not nervous about it at all.
"In fact, getting a start like this has calmed our nerves. The team's only going to get stronger and we're on the up and up.
"So we'll be going into the game in a happy frame of mind and ready for the challenge."
With another tough game against Croatia also ahead, it was important Mexico started with a victory.
Ochoa, who plays for French club Ajaccio, said: "Our opponents made it a tough game and the conditions made it even harder.
"When you get rain like that it makes life difficult for goalkeepers, but I'm happy with the result."
Ochoa was making his World Cup debut after being an unused squad member in the last two tournaments.
He had little to do throughout the game but produced a good save in injury time to keep out a Benjamin Moukandjo header and preserve the three points.
He said: "I'm pleased I was able to help out my team-mates on the pitch and to have made my debut at last.
"I was alert and luckily I was able to chip in with my save.
"The important thing is that we showed how brave we can be. The team looks pretty strong mentally."
