Manchester City-bound forward Gabriel Jesus scored one and set up another as Brazil made it six wins in a row with a 2-0 victory over Peru.
Not since qualifying for the 1970 World Cup have Brazil won six South American qualifiers in a row, but Ttie's side put in another impressive display in Lima to keep a fourth clean sheet in as many games.
Having thrashed rivals Argentina 3-0 last week the Samba Boys might have expected to make light work of Peru, but they were frustrated for the opening 45 minutes.
Jesus, who has agreed a move to the Etihad Stadium in January, finally broke the deadlock in the second half and then set up Renato Augusto late on.
The five-time World Cup winners are now four points clear in the South American group, while defeat leaves Peru eighth and unlikely to reach Russia 2018.
