Midfielder Paulinho insisted on Wednesday that the Samba stars were on the right track ahead of their opening game.

'The pressure on Brazil will always be there,' said the Barcelona man. 

'It was there for the last World Cup. We were under pressure. But what we did in the last four years was to leave the past behind us. We lost and this is another chance. We have an opportunity to be better.

'We know how difficult it's going to be. Opponents are watching us because we are playing consistent football. Most important, we are playing a happy kind of football. We have to play like that. Happy. We do what we love.

'We are on the right track and we are focused on a having a wonderful World Cup.'
