#4 The most meetings between two teams
Three pairs of teams hold the current record for the most meetings between two teams. They are Brazil and Sweden (1938, 1950, 1958, 1978, 1990 and twice in 1994), Germany and Yugoslavia/ Serbia (1954, 1958, 1962, 1974, 1990, 1998 and 2010), and Argentina and Germany (1958, 1966, 1986, 1990, 2006, 2010 and 2014). Moreover, the pair of Argentina and Germany hold the record for the most meetings between two teams in the final of FIFA World Cup.
This year, all the four teams have made it through to the World Cup. Now, if Germany finishes at the top of their group and Serbia finishes second, or vice-versa, they would meet each other at the Round of 16. The same scenario also holds if Brazil tops their group, and Sweden finishes second, or vice-versa. Meanwhile, if Argentina and Germany top their group and win the subsequent Round of 16 matches, they would meet each other at the quarter-final.
Like the previous record, there is a high chance that this record might also be broken.
