Algeria are hanging on a bit here. Gervinho, who is enjoying one of his better days, cuts inside his man on the edge of the box and draws a save from Rais M'bolhi.
A breakneck start to this second half. Algeria build cleverly in attack but they turn the ball over and Ivory coast break at speed, Serey Die almost releasing Gervinho. The pacy winger just fails to bring the through-ball under control.
Algeria were out on the pitch three minutes before Ivory Coast. Christian Gourcuff obviously kept his half-time team-talk short and sharp. But will it work? We're about to find out...

"I think we all agree that the standout moment of the tournament so far is Herve Renard having to wear his pink bib. Right now he is customising it, he has a pair of scissors and he is cutting the bib. He is making absolutely sure that if he is going to have to wear it, he will wear it well."
Football writer Jonathan Wilson:, external Ivorians have shut it down well since taking the lead.
These two sides are competing for a place in the semi-final against DR Congo, so whoever prevails here will be a heavy favourite to make the final.
Algeria were so impressive as a relative outsider at the 2014 World Cup, but has the weight of opportunity stifled their creativity here?
Ivory Coast have underachieved in major tournaments on many occasions, but Herve Renard's side don't seem haunted by past failures.
Jake Cullingham:, external As a Leicester fan, Algeria's Mahrez is very underrated. He's helped Algeria through this comp and is shining in the Premier League.

"I think Ivory Coast started off very slowly. I don't remember them being in the Algeria half for the first 15 minutes but they started building and got the goal through Wilfried Bony.
"Algeria came out and really dominated the game early on and maybe they should have made more of the ball when they had it. The Ivorians have grown in confidence."
A fairly even first half in this blockbuster quarter-final, but the telling difference between these two heavyweights has been Ivory Coast's greater threat in front of goal.
They lead courtesy of Wilfried Bony's first goal at Afcon 2015. Can they hold out?
Algeria's Sofiane Feghouli drills in a dangerous cross, and Kolo Toure, taking no chances, puts it behind for a corner. The inswinger is well claimed by Sylvain Gbohouo. Two added minutes.
Another long-range effort, this time at the other end. Saphir Taider unleashes a venomous swerving effort, but it's straight at Sylvain Gbohouo. The Fennecs have struggled to pose a goal threat in this half.
The newly emboldened Wilfried Bony tries his luck from 25 yards, but he slices across the ball and his low drive skids wide.
obasi chidi:, external Game isn't over Yaya & Bony should know that Algeria can outsmart the Ivorian's.
Ivory Coast are quite content to sit in here, challenging Algeria to break them down. Algeria coach Christian Gourcuff looks nonplussed on the sidelines, even more so after Saphir Taider lumps a free-kick straight out of play.
A bit of a lull in the action in Malabo. It's been a fairly even first half after Algeria's dominance in the first 10 minutes.
Algeria were briefly under the cosh there, but they've recovered their composure well. They're playing the ball around comfortably in midfield, but can they get through those banks of orange?
How's this for commitment? Algeria skipper Madjid Bougherra, who is playing with a broken nose, has taken off his protective face-mask. Remember, this will be his last international if Algeria lose.
Are Algeria missing Islam Slimani's physical presence up front? It does seem that way. Yacine Brahimi is nimble, but he's well marshalled by Kolo Toure.
JavelBleach:, external Stupid from the Algeria keeper, signalling offside & not bothering to save the goal! 1-0.

"Algeria were the better side for the first 20 minutes but they did not create the best chances, Ivory Coast had two of the better chances and took one of those but Algeria will not give up hope. They have come back before in this tournament against South Africa."
