ZURICH, Switzerland -- Argentina remained the top-ranked team in FIFA rankings and the rest of the top 15 stayed unchanged.
Brazil remained second, followed by world champion Italy, Spain, Germany, Czech Republic, France, Portugal, Netherlands and Croatia. European champion Greece stayed 11th and England remained 12th.
Nigeria moved up one place to 19th -- swapping places with the United States -- after beating Sudan 2-0 in an exhibition Jan. 9.
Nigeria has 879 points -- three more than the 20th-ranked United States, which has not played since defeating South Africa in an exhibition Nov. 17.
With European and South American teams idle in December and early January, there were few moves in the rankings.
