As things stand Congo and Equatorial Guinea go through.

Gabon need one goal and Burkina Faso need two.

Finally Burkina come to life! Aristide Bance's low cross from the right is touched back to Chelsea starlet Bertrand Traore, who steams onto it but puts his finish wide of the post. Was that their chance?

It's almost the moment Equatorial Guinea clinched their place in the quarter-finals, Javier Balboa is found in acres of space in the box - he attempts to just slot the ball past Didier Ovono, but the keeper saves it down low.

Gabon are on the brink here.

The change is made as Juvenal Edjogo-Owono, a 35-year-old defensively minded player who plays in Andorra, comes on for striker Raul Fabiani.

Another change for Congo - Ferebory Dore, who made the goal, makes way for Fabrice Ondama.

Confusion as Juvenal Edjogo-Owono is ready to come on but the fourth official holds up the wrong number. He shows number 21, Ivan Zarandona's number but that's not who the hosts' coach wanted to bring off. Play goes on with no change made.

Congo win a free kick in the left corner and it almost brings them a second. The ball is rolled across the edge of the box to Delvin N'Dinga, who meets it with a crisp strike that Germain Sanou does well to get down to.

"Massive frustration for Bance, who flicks the header into the penalty area, only to see Pitroipa lurking about 10 yards behind him. That's not going to get them back into this game as time ticks down and Bance makes his unhappiness very obvious."

Viera Ellong forces a save from Didier Ovono - Equatorial Guinea are pushing for a second here.

Gabon really need Pierre-Emerick Aubameyang to come up with a piece of magic now. Eighteen minutes left.

Congo are not sitting back on their lead and are passing the ball around with confidence in the opposition half. Burkina Faso, by contrast, look resigned. Can they summon a late fightback?

Gabon now make a change as forward Ibrahim N'Dong comes on for midfielder Andre Poko, who had a terrible effort on goal in the first half.

Equatorial Guinea make a change as Valencia teenager Iban comes on for Kike, who also plays in Spain for Mallorca.

Big penalty shout from Burkina Faso, but Jonathan Pitroipa's cross strikes the midriff of Francis N'Ganga. Optimistic from the Stallions, but who can blame them - they look desperately short of ideas.

Andrew Lee: Thievy Bifouma is definitely the best Congolese player since defender Christopher Samba.

Antonio Martinez: If Congo advances and goes far in Afcon, they certainly will have atoned for missing out on 2014 World Cup.

Heads are gone for Gabon. They concede the ball cheaply and Equatorial Guinea can sense a potential second goal on the cards here. It comes to nothing but the volume levels are very high in Bata - the home fans can sense a shock on the cards here.

Goalscorer Thievy Bifouma is hooked - Ladislas Douniama comes on for Congo. Bifouma gets a well-deserved hug from Claude Le Roy.

"So Paul Put has played his double trump card... Aristide Bance and Bertrand Traore are both on for Burkina Faso with just under an hour to go now. They need to get back into this game or they're off home. But the neutrals in the crowd here in Ebebeyin are still celebrating their home nation going in front in Bata. The volunteers did a lap of honour in celebration! Their boss wasn't impressed, but they didn't care."
