Brazil won the world cup in 1994. Before that, he had won this title for the last time in 1970.

If you add up: 1970 + 1994 = 3964
Argentina won the world cup for the last time in 1986. Before that only in 1978.

And 1978 + 1986 = 3964
Germany, though, won the world cup in 1990. Before that, Germany won in 1974.

Look: 1990 + 1974 = 3964

This could lead us to guess the winner of the World Cup in 2002,
since it should be the winner of the 1962 World Cup (In fact 3964 - 2002 =1962).
And Brazil won the world cup in 1962! (And, in fact, Brazil won>the 2002 WC) This numerology seems to work...

؟And now, who would be the winner of the 2006 world cup

Let's see, 3964 - 2006 = 1958

?…..and who won in 1958

Oh, Brazil did!!!
