Wilfried Bony was the star turn as the Ivory Coast beat tournament favourites Algeria 3-1 to reach the last four of the African Nations Cup.
Showing the sort of form which persuaded English champions Manchester City to pay Swansea £25million in the January transfer window, Bony produced two excellent headers - one in each half - to hand the Ivory Coast a semi-final date with DR Congo.
Bony struck from close range to give the Elephants a 26th-minute lead and, after Hilal Soudani had equalised soon after the re-start, the muscular frontman rose majestically to meet Yaya Toure's free-kick after 68 minutes.
And Gervinho, restored after a two-match ban for his red card against Guinea, punished Algeria's all-out attack in the closing stages with a third Ivory Coast goal deep into stoppage time.
That was tough on Algeria who had contributed so much to an entertaining contest in Malabo and almost levelled in the final 10 minutes through Islam Slimani and Faouzi Ghoulam, the latter's free-kick forcing a sprawling save from Sylvain Gbohouo.
Ghana reached a fifth successive African Nations Cup semifinal as they breezed past Guinea 3-0 in Malabo.
Avram Grant's Black Stars will now play hosts Equatorial Guinea on Thursday after Christian Atsu scored twice and Kwesi Appiah added another to complete a routine win.
Guinea's misery was completed when goalkeeper Naby Yattara, who had been booked in the first half for shoving Atsu, rushed out of his goal in the fourth minute of injury time and was sent off for flattening Asamoah Gyan with a wild kick.
Yattara had beaten as early as the fourth minute by Atsu and Ghana were heading for the last four when Appiah scored on the stroke of half-time to give the Black Stars a two-goal cushion.
Ghana's progress was confirmed after 61 minutes when Atsu delivered a wonderful dipping shot which gave Yattara absolutely no chance and posted a contender for goal of the tournament.
Guinea only made the quarterfinals after winning a drawing of lots on Thursday to emerge from Group D at the expense of Mali, but they had failed to beat Ghana in this competition in five attempts and never looked looked like breaking their duck.
