Nigeria win a corner inside 15 SECONDS!

There's a terrific atmosphere inside the Alexandria Stadium.

I've already spotted two saxophones in the crowd. Plenty of fans with trumpets too. There's passion and vibrancy all around the ground.

Nigeria and Cameroon have won Afcon EIGHT times between them.

One of Africa's super-powers will be on their way home tonight. Who will it be?

We're under way.

When the Confederation of African Football (Caf) chose to move the Nations Cup from January-February to June-July two years ago, it was immediately clear that there would be knock-on effects for the tournament.

January has the lowest average temperature across the continent and May the highest, while in certain countries – such as Egypt – the highest heat of the year takes place in July itself (an average of 27.5 degrees).

This year’s Nations Cup, which started on 21 June, will climax on 19 July in Cairo but thankfully for the players, playing in the intense heat of the afternoon is now a thing of the past after the group stages’ 36 games ended.

This has been a red hot tournament - and not just because Madagascar and Benin have turned up to the party to deliver surprise wins.

The temperatures during matches have become a hot topic of conversation but it's a fairly cool evening in Alexandria where it currently is 18C (64F).

Another start in Nigeria's defence for Kenneth Omeruo.

This week he became Chelsea's longest serving player having signed for the Blues in 2012.

Yet he has spent much of the last seven years out on loan around Europe and is still to make a Premier League appearance for Chelsea.

Nigeria boss Gernot Rohr responds to his side's shock defeat to Madagascar on 30 June by making FIVE changes.

Nigeria XI: Akpeyi, Awaziem, Troost-Ekong, Omeruo, Aina, Ndidi, Etebo, Iwobi, Simon, Ighalo, Musa.

Just the three changes for Cameroon, who include Paris St-Germain's ex-Stoke City forward Eric Maxim Choupo-Moting.

Cameroon XI: Onana, Banana, Ngadeu, Collins, Oyongo, Mandjeck, Malong; Njie, Choupo-Moting, Bassogog, Bahoken.

Welcome to day 16 at the Africa Cup of Nations!

We have an absolute humdinger of a game in Alexandria between two giants of African football - reigning champions Cameroon against three-time champions Nigeria.

For the winners, a trip to Cairo to face hosts Egypt or South Africa, who play later, in the quarter-finals.

For the losers, it's the end of the road.

Their Africa Cup of Nations triumph of 2017 already seems an age ago.

Cameroon have stuttered in Egypt, failing to win - or score - in their last two games.

Now they're up against a Nigeria side desperate to be crowned champions for the first time since 2013.
