PREDICTING SUCCESS WITH THE FIFA WORLD
RANKINGS
28/11/01
by Jeff Dieffenbach
Since August of 1993, FIFA has been drawing up monthly rankings
of the world’s national teams. On the eve of the December 1 draw in
Busan, Korea Republic to determine the groupings for the upcoming
2002 playing of the 17th World Cup, the latest round of such
rankings are now complete.
The rankings consider a broad range of matches over the previous
eight years: World Cup qualifiers and finals, continental
championship qualifiers and finals, Confederations Cup matches, and
international friendlies. For these matches, rankings factor in game
outcomes (both result and score), location, and importance, plus
opponent and regional strength.
On the surface, a reasonable approach, although some might argue
that the eight-year window is too long. While only ceremonial in
nature, it is worth holding these rankings up to the light of actual
World Cup results.
In 1993, Germany, Italy, Brazil, and Norway
topped FIFA’s December rankings. All four qualified for the 24-team
1994 World Cup in the United States, but number six Denmark did not.
Other teams ranked in the top 24 that failed to make the finals
included France (15), Uruguay (17), Czechoslovakia (19), Portugal,
Colombia, and Scotland. Note that all are European or South
American.
For the teams that did qualify, did their FIFA ranking correlate
to World Cup performance? A decided no. In fact, the correlation
between seeding based on FIFA ranking coming into the draw and final
team performance was a pitiful 0.35 (For details of how this
analysis was conducted, see the discussion at the end of this
article. Readers interested in learning more about statistics might
consider getting out of the house more.)
Who rose above expectation, and who failed to perform? Powers
Brazil and Italy played true to form, and well: Brazil came in
seeded 3rd and proceeded to win the tournament (+2 spots); Italy
arrived 2nd and finished 3rd (-1).
Bulgaria and Saudi Arabia emerged the proudest of their
performances, rising from 20th to 4th (+16) and 22nd to 9th (+13),
respectively. On the disappointing end, Norway fell from 4th to 13th
(-9) and Colombia plummeted from 9th to 18th (-9). (Recall that
Colombia’s woes would soon turn to tragedy with the subsequent
gambling-related murder of star Andres Escobar.)
In 1997, FIFA’s December favorites included
Brazil, Germany, the Czech Republic, and England. Missing again from
the 32-team tournament in France was the Czech Republic (FIFA rank
of 3), joined on the sidelines by Russia (12), Sweden (18), Bolivia
(24), Ecuador (28), Portugal (30), and Egypt (32). Again, Europe and
South America took the bulk of the absences.
Measured against actual performance, FIFA’s rankings predicted
actual results even more poorly than in 1993 with a dismal
correlation of 0.30.
As in 1993, Brazil and Italy once more played true to form, and
once more played well: Italy entered as the 8th seed and finished
6th (+2); Brazil came in 1st and finished 2nd (-1). Likewise, France
triumphed from the number 5 spot (+4).
Nigeria outplayed its seeding by the largest margin, moving from
32nd to 11th (+21). Croatia, though, was the surprise of the
tournament, climbing from the midpoint (16th) all the way up to
number 2 (+14). Other surprises? USA’s fall from 21st to a tie for
last (31, -10) and Japan’s collapse from 12th to 31 (-19).
What of 2001’s rankings? The Czech Republic
misses out for a 3rd consecutive time (rank: 13), along with
Colombia (5), The Netherlands (8), Yugoslavia (12), Romania (15),
Norway (25), Honduras (26), Iran (29), and Trinidad & Tobago
(tie 31). Once again, note the hit suffered by Europe and South
America.
The last entry in the “missing” list highlights the failings of
the FIFA rankings. How can Costa Rica, a strong winner of CONCACAF
qualifying with 23 points in 10 games, be tied at 31st in the world
rankings with Trinidad & Tobago, who finished last in the same
qualifying group with only 5 points? The answer is quite simple—the
(inflated?) importance of past results. Only a year ago, Costa
Rica’s world ranking stood at 60 compared to T&T’s 29.
Brazil (seeded 3rd) and Italy (6th) would seem poised to end
among the tournament’s leaders. France also, as the top seeds have
fared well (Brazil finishing 2nd in 1998 and Germany finishing 5th
in 1994).
Only the games will determine the rising stocks and falling
stars. At number 20, the United States has room to move … in either
direction.
Next: Why do Ranked Teams Fail to Qualify?
# # # #
How the analysis was conducted: The author examined FIFA rankings
for December of 1993, December of 1997, and November of 2001 (the
end of the year prior to the following year’s World Cup final). The
qualifying field was then seeded based on these rankings.
The difference between seed and rank reflects teams that did not
qualify. For instance, if the third ranked team did not qualify (as
was the case with the Czech Republic in 1998) but the first, second,
and fourth did, the 4th ranked team would have its World Cup seed
elevated by one to 3rd due to the absence of the third ranked
team.
Final World Cup performance was based on accumulated points:
three for a win, one for a draw, none for a loss. No accounting was
made for goal differential or match importance. For instance, Brazil
and Croatia tied for second in the 1998 World Cup based on 2-1-0
record in their groups and three subsequent wins for a total of 15
points. Brazil’s semifinal win over The Netherlands and its loss in
the final to Brazil is given equal weight to Croatia’s semifinal
loss to France and its bronze medal (3rd place) win over The
Netherlands.
Correlation was arrived at by performing a linear regression of
seeding versus actual performance.
