Brazil striker Neymar says the five-time champions are dreaming of winning the World Cup again in Russia.
The Paris St-Germain forward scored his 55th international goal to go level with Romario and sit joint-third in Brazil's all-time scoring charts during their 3-0 win over Austria on Sunday.
Gabriel Jesus and Philippe Coutinho also netted in a comfortable victory ahead of Brazil's opening World Cup game against Switzerland on Sunday.
"You have to trust, you dream," Neymar told reporters. "You can talk, you're Brazilian and you can dream; we're dreaming more and more. Dreaming is not forbidden."
Manchester City striker Jesus also insisted Tite's side are ready for the tournament.
"All the games before the World Cup were important to reach this level of performance," said Jesus, who now has 10 international goals.
"Austria had quality and we knew it would not be easy. We managed to play, involve their team and make another big game. Not only was the attack well, the group went very well."
Brazil had spent 10 days preparing at Tottenham's training ground and beat Croatia 2-0 in Liverpool last week before this victory.
Jesus opened the scoring nine minutes before the break when he curled in from an angle.
Neymar struck just after the hour as he bamboozled the Austria defence to score and Coutinho wrapped the victory up minutes later.
"The game was important to us. It was the last game of preparation before the World Cup. We deserved the victory, we played very well," added Coutinho.
"That gives you confidence. I always try to be prepared to play where the coach needs me and contribute in the best way possible."
Neymar joked about Austria's rough approach: "We got ready for the UFC today, but it was good. Everyone was unharmed."
