The Pharaohs: From top 10 to 57th
The Pharaohs played once in October, defeating Zambia 3-0 in a friendly amid preparations for the 2018 World Cup qualifiers this month. But this didn't help them win a better ranking.
Under the helm of Argentinean manager Hector Cuper, Egypt will play Chad twice this month, on 14 and 17 November, in attempt to win their first ticket to the World Cup since 1990.
The winners of a record seven African Cup of Nations (CAN) trophies, Egypt is also competing in Group G of the 2017 African Cup of Nations qualifiers as they recently defeated Chad 5-1 away from home.
Chad was named best mover of the month in the FIFA rankings, bouncing from 175th to 138th.
Egypt has failed to reach Africa's showpiece three times in a row, the first time the team missed at least two consecutive tournaments since failing to qualify for the 1965 and 1968 CAN.
Egypt earlier made it into FIFA's top 10 after winning three successive African Cup of Nations trophies, in 2006, 2008 and 2010.
