Midfielder Geremi Njitap scored at the second attempt from a penalty to give the 'Indomitable Lions' a half-time advantage against Togolese opponents led by reigning African Footballer of the Year Emmanuel Adebayor. However, the Manchester City striker was substituted 15 minutes into the second half after goals from Jean Makoun and Achille Emana had given Cameroon a 3-0 cushion.
Makoun netted off a pass from Inter Milan striker Samuel Eto'o, who dribbled past four defenders, and Emana beat overworked goalkeeper Kodjovi Obilale with a low drive. A Cameroon side transformed by the mid-year arrival of French coach Paul le Guen have 10 points, Gabon nine, Togo five and Morocco three and the Lions cannot be overtaken if they triumph on 14 November in Rabat.
Hicham Mahdoufi conceded an own goal on the stroke of half-time to give Gabon a lead they stretched during the second half through Eric Mouloungou and Daniel Cousin before Adel Taarabt snatched a late consolation goal.
Egypt, meanwhile, kept alive hopes of overtaking Group C pacesetters Algeria with a narrow 1-0 victory in Zambia courtesy of a mid-second half strike from midfielder Hosny Abd Rabou. Algeria (plus five) lead Egypt (plus three) on goal difference and will regain a three-point advantage if they defeat bottom-of-the-table Rwanda in Blida Sunday.
