Belgium has moved ahead of France to take outright top spot in FIFA’s world rankings released on Thursday.
Tiny Gibraltar were the biggest risers, thanks to their first two competitive wins this month.
Belgium and France had been tied at the top last month.
While both sides won one game and drew another in October, the Belgians, with 1,733 points, moved ahead by a single point under the formula for calculating the rankings.
Belgium beat Switzerland in the UEFA Nations League and drew with the Netherlands in a friendly.
World champions France defeated Germany in the UEFA Nations League and were held by Iceland in a friendly.
Brazil, one of only two non-European sides in the top 10 along with Uruguay, remain third, followed by Croatia and England.
Gibraltar, who only became FIFA members in 2016, rose eight places to their best ranking of 190th thanks to their UEFA Nations League wins in Armenia and at home to Liechtenstein.
Madagascar, who earlier this month qualified for their first African Nations Cup finals, climbed into the top 100 for the first time since 2002, after being ranked 100th.
Tunisia, 22nd, were the highest ranked African team and Iran, 30th, the top Asian side.
