Another almost chance for Nigeria. Ahmed Musa speeds down the left and tries to find Odion Ighalo but the Chinese-based former Watford striker can't control it.

Look out for Guinea’s number 16 Ibrahima Traore, wearing the captain’s armband. He was literally discovered on the streets. He’d been rejected by all the French clubs but was playing a game of street football with his mates near his house in Paris.

An agent with German connections happened to be playing too. He was so impressed that he got Traore a trial at Hertha Berlin. The rest is history.

Wilfried Ndidi fouls Premier League rival Naby Keita and Guinea have a free-kick. Now Odion Ighalo is fouled and Nigeria get a free.

Almost a chance for Nigeria but the ball just won't land kindly at the feet of Alex Iwobi. If he could have got a proper touch on that, he'd have had a great scoring chance.

Corner to Nigeria now, won by the pace of Moses Simon. A very open start here.

Guinea clear the corner.

First chance of the game is to Guinea. Ibrahima Cisse lines one up about 25 yards out but his swerving bouncer is parried away by Daniel Akpeyi.

We are under way in Alexandria.

Nigeria top Group B after an opening 1-0 win over tournament debutants Burundi. Guinea drew 2-2 with other Afcon new boys Madagascar.

The top two go through to the last 16, along with the four best third-placed teams. Same format as the Women's World Cup and Euro 2016.

A bit of a risk from Guinea boss Paul Put to start Naby Keita. He said he was only fit enough for 30 minutes on Saturday.

Things can’t have changed that much in four days. Still, after they drew their opener v Madagascar, Guinea are under pressure to get a result. They need Naby at his best.

John Obi Mikel didn’t play well v Burundi but remember yesterday he convinced the players to train when they were upset about not receiving their match bonuses.

Dropping a big personality like Mikel is a gamble from Nigeria boss Gernot Rohr. How he reacts to the decision could have a big say in how they do in Egypt.

Guinea midfielder Naby Keita makes his first start since Liverpool's 3-0 defeat by Barcelona in the Champions League semi-final second leg (which seems like a long time ago).

He has recovered from the groin injury which ruled him out for the final five games of the English season, including the Champions League final win over Tottenham.

John Obi Mikel is dropped by Nigeria.

I’ve just arrived in Alexandria and a fascinating stadium that’s said to be the oldest in the country.

The VIP section is in what looks like a cricket pavilion behind the dugouts (Kanu is sitting up there on a throne - literally).

There’s what looks like the remains of a castle in one of the corners and the athletics track surrounding the pitch means there’s a big distance to the fans behind one of the goals (only beaten by the distance at the Withdean Stadium back in the day).

The pitch meanwhile is an absolute beauty.
