I think this is a hat on a fan in the stadium. I hope whoever brought that in gets the result they want. Such effort should be rewarded.

We go into the final 20 minutes.
I think this is a hat on a fan in the stadium. I hope whoever brought that in gets the result they want. Such effort should be rewarded.
Pierre-Emerick Aubameyang is slid into the left-hand channel. He checks back and a shot is all that's on his mind. It's a curler and it's narrowly off target. He looks slick, if a little rough around the edges.
BBC Sport's Nick Cavell in Bata: Gabon coach Jorge Costa seems to have picked up a love for officials from his mentor Jose Morinho - Costa has been at the fourth official and the referee for the whole match.
Great chances at both ends. We should have had two goals.
First Gabon's Frédéric Bulot is picked out with a left-wing cross and pulls the ball down on the penalty spot...chance to put his side two up...straight at the goalkeeper. But he should be made to pay as the brilliant Bertrand Traore races down the left - he skins his man and races away Gareth-Bale style...he's through...saved.
The goalkeeper stood tall and as Traore closed in from the angle, his shot can't squeeze in the near post. A massive couple of moments in this game.
Alain Traore takes measure from 20 yards...whips it...Didier Ovono is scrambling in his goal...nope.
Just over the bar. A yard at most. The hour has ticked past. Gabon will be overjoyed if this holds.
Now then, Jonathan Pitroipa is felled around 20 yards from goal. Alain Traore has just had an effort from a free-kick as a warm-up for this...
Bertrand Traore is actually a Chelsea player - albeit on loan at Vitesse.
He has been lovely to watch here so far and at just 19, looks athletic, quick, tricky, you name it.
He skips around his marker with hardly any space to operate on the dead-ball line. His cross is powerful and turned behind by the goalkeeper. One to watch this lad.
Who should win this game and why is it so nicely poised?
Only two places separate the teams in Fifa's world rankings and they met in qualifying, so margins, you would think, will be small.
instead we get a corner at the other end after some powerful running from Pierre-Emerick Aubameyang. A whipped delivery can't be reached by Bruno Ecuele Manga and is headed clear.
Both of these sides do not really like (or perhaps do not have the ability) to keep possession for long. Attacks are quick and focused as opposed to slowly built.
The combination of Traores - Alain and Bertrand - and Jonathan Pitroipa looks vibrant and you would think they will again cause problems in this second half.
Gabon defend narrowly when they come under threat. It's organised to an extent, but you get the feeling a well-timed run and pass could catch them square as they like to hold a line.
Traore - of the Bertrand variety - forces a corner does he...no...goal kick.
Here we go then. The first game we saw involved a second-half fight-back. Will we see the same again?
The ball in rolling, Estadio de Bata is still simmering nicely and Burkina Faso attack early in the second half...
Rizzi:, external Both teams playing attacking football with really shaky defences, great for a neutral but Ghana will win the tournament.

The half-time stats showcase Burkina Faso's poor finishing...

BBC Sport in Bata
"Dider Ovono has been the star of the show for Gabon despite Pierre Emerick Aubameyang's goal. The keeper has twice saved brilliantly from Jonathan Pitroipa, top scorer in qualifying and player of the tournament two years ago. Ovono also did well to palm away a powerful Bertrand Traore drive. Gabon look very good on the ball, Andre Poko has moved swiftly and effectively between defence and midfield. Burkina Faso have had more chances, they've lacked the coolness Aubameyang displayed at the other end."
BBC Sport's Nick Cavell in Bata: The contrasting styles of the coaches - Paul Put in tracksuit topped with a pink Caf bib while Jorge Costa has gone smart casual with tie shirt and black shoes. Not quite the full suits we saw in the first game from Claude LeRoy and Esteban Becker.
Harsh? Maybe. But Pierre-Emerick Aubameyang showed he does not play for one of Europe's top clubs for nothing.
The Borussia Dortmund striker punished a lapse at the back for Faso with a clever finish (and an even cooler celebration - see below).
Faso - beaten finalists in the last AFCON - have had shots and chances aplenty but they need to discover their own clinical streak.
Chewe Puta:, external This is a fantastic game, both #Burkina and #Gabon are playing with heart.
Andrew Priestley:, external Pierre-Emerick Aubameyang is a real form player, when he's up for it he hits hot streaks. This could be his tournament.
Going forward there is no doubt Burkina Faso have a few tricks up their sleeve. Bertrand Traore this time collects a pass in the right channel and cuts in on his left foot to shoot at the near post.
Didier Ovono is equal to and collects his parry at the second attempt. The Traore contingent all want a crack..this time Alain Traore volleys over.
