Cote d'Ivoire earned a dramatic win over Congo DR in an Africa Cup of Nations qualifier while Nigeria slumped to a lacklustre defeat against Sudan.
Max Gradel's late goal secured a hard-fought 2-1 triumph for Cote d'Ivoire in its latest Cup of Nations qualifier.
Herve Renard's side had suffered a humiliating 4-1 defeat to Cameroon last time out, but got back on track in Group D by claiming three points in Kinshasa.
Wilfried Bony failed to convert an early penalty after a foul on Yaya Toure, but the Swansea City forward soon made amends by glancing home the opener from Serge Aurier's cross.
The host pushed hard to restore parity and was rewarded for its efforts when Evian defender Cedric Mongongu scored a 71st-minute spot-kick.
However, it was St Etienne winger Gradel who had the final say, striking the winner with just seven minutes remaining.
Elsewhere in Group D, leader Cameroon saw its 100 per cent record come to an end with a 0-0 draw against Sierra Leone.
Pressure is mounting on Nigeria coach Stephen Keshi after his side suffered a 1-0 loss to Sudan in Khartoum.
Bakri Abdelgadir's powerful 41st-minute header – Sudan's maiden goal in this qualifying campaign - was enough to seal a shock success for the host.
Keshi's reigning African champion was devoid of ideas going forward and failed to break down a stubborn Sudan defence, although John Obi Mikel did have a goal chalked off for offside.
