Under Tite's watch, Brazil reached the quarterfinals of the 2018 World Cup, where it lost 2-1 to Belgium.
When Tite took over in June 2016, Brazil was still reeling from the heartbreak of its 7-1 loss to Germany in the 2014 World Cup semifinals. The Selecao were also sixth in CONMEBOL for World Cup qualifying.
Keeping Tite in the short term makes sense. He has brought much-needed stability to the national team and turned Brazil into more than a one-man team heavily reliant on Neymar's playmaking and goalscoring. Plus, Brazil will want to win the 2019 Copa America on home soil.
Having said that, the track record for coaches returning for a second World Cup cycle is a mixed bag.
Oscar Tabarez is going on 12 years with Uruguay and continues to enjoy success with La Celeste, but he's among the exceptions.
After winning two European Championships and a World Cup under Vicente del Bosque, Spain crashed out of the 2014 World Cup in the group stage. Del Bosque resigned after Spain lost in the round of 16 at Euro 2016.
Marcello Lippi stepped down as Italy's coach after the Azzurri won the 2006 World Cup. He returned to lead the team into the 2010 World Cup, where Italy finished last in its group.
The same result befell 2006 runner-up France as Raymond Domenech stayed on for a second consecutive tournament. It took years for France to recover from the open revolt that the players waged against Domenech in South Africa.
Tite is an excellent coach, something he cemented when he led Corinthians to Copa Libertadores and Club World Cup titles in 2012. But he might struggle to overcome the complacency that generally sets in for national teams going through a second World Cup cycle under the same manager.
