Former West Ham attacker Sebastien Haller scored twice in nine minutes to give the Ivory Coast a 2-1 World Cup qualifying win over fellow African top-10 nation Cameroon in Abidjan on Monday.
Haller, who moved to Ajax Amsterdam last January after scoring 14 goals in 54 outings for the Hammers, converted a penalty on 20 minutes and later outpaced a defender and fired into the far corner of the net.
Moumi Ngamaleu pulled one goal back from another penalty, on 61 minutes, to set up a tense finish to the Group D showdown.
Ivory Coast top the table with four points after two rounds, Cameroon have three, and Mozambique one and Malawi none ahead of their match on Tuesday.
Group D is the only section of 10 in Africa featuring two countries among the 10 highest ranked in the continent — the Ivory Coast were 12th when the draw was made two years ago.
Meanwhile, South Africa edged Ghana 1-0 in Johannesburg through a 83rd-minute Bongokuhle Hlongwane goal and replaced them as Group G leaders.
