Let’s see. Arguably, the three natural candidates are: a. Brazil: Five-time champion, two-time runner up, and number 2 on FIFA’s men’s ranking. b. Germany: Four-time champion (current champion) three-time runner up, and number 1 on FIFA’s men’s ranking. c. Argentina: Two-time champion, three-time runner up, and number 4 on FIFA’s men’s ranking. They also have Lionel Messi, the most talented player in the world who, as an adult, is yet to win a title with Argentina. Now, considering that the only time a South American team has won a World Cup in Europe was in 1958, I would say Germany will win the 2018 World Cup.
