Brazil, the 2014 World Cup hosts, continue their preparations for the tournament with a friendly against Japan in Poland on Tuesday.
The South Americans have put 14 goals past their last two Asian opponents with a 6-0 triumph over Iraq last Friday following on from an 8-0 belting of China.
But despite their formidable form, coach Mano Menezes insists there's still room for improvement.
"Yes. We are unbeatable for the last 14 months, but on the other hand the expectation on Brazilian football is always huge," he said.
"We are getting closer to what we want. That's the last part of the process and our game itself is already better."
Menezes may be without fullback Marcelo and midfielder Ramires through injury and illness respectively, but the recently recalled Kaka may feature.
Japan will be looking to cause their second upset in a week at Municipal Stadium in Warsaw after they recorded a 1-0 win over France last Friday.
Alberto Zaccheroni's men have only lost twice in their past 15 fixtures in all competitions and have all but qualified for the 2014 tournament.
But he is rightly anticipating a much bigger challenge from the five-time World Cup champions.
"Brazil are the team I consider the most 'technical' in the world. They combine these skills and an offensive mentality with good dynamism," Zaccheroni said.
"Our plan is to play openly, but we are not the only team on the pitch. Brazil along with Spain are considered the best team in the world.
"They are preparing for next World Cup at home. I also think they are the favourite at the next World Cup since they play at home and they have so many talents."
