#1 Brazil
Brazil is not only the biggest non-European candidate, is the biggest candidate - period.
The Tite-led squad is in phenomenal form since the new boss walked in as Dunga's replacement. In 20 games with Brazil, Tite hasn't lost an official game. Brazil has won 16 of their 20 games under Tite, with three draws and one loss (vs Argentina in a Friendly Match, without Brazil's main names).
Neymar is Brazilian's hope, and it is well deserved for the magical number 10.
The PSG star will be the star for the Brazilians in the 2018 World Cup, even though he sustained a foot injury and did not play an official game since February, his great return in a friendly against Croatia made Brazilian's hopes increase.
Neymar is fourth all-time in the Brazilian goalscorers table with 54 goals, behind Pelé (77), Ronaldo (67), and Romario (55).
Alongside Neymar, Brazil has players like Real Madrid legend Marcelo, the hardworking Casemiro, Paulinho, Philippe Coutinho, Willian, Douglas Costa or Gabriel Jesús. The Brazilian national team is definitely a squad to look after in the World Cup, and probably many teams consider the Scratch du Oro as the team to beat in Russia.
