Colleague Andy Cryer states: "Shall we just say this is 0-0 now then?" He said that last night and we had two goals in a matter of minutes.
Our England-based four are not grabbing this by the scruff of the neck so far.
Dean Furman (pictured bottom right) has probably shown the most of the four but Tokelo Rantie, Riyad Mahrez and Nabil Bentaleb are not dictating. Just as I say that, Furman switches off and allows an opponent to get a shot in but it drifts over.
BBC Sport's Matthew Kenyon in Mongomo: You could feel the reverberations of the bar from Furman's shot from where I'm sitting... They've really come into this one now, Bafana Bafana. Quieter atmosphere for this one - except when there's a chance. Then everyone bounces back to life... and the drums have changed. They're still there - but the big bass drum has been replaced by a quicker tempo...
Riyad Mahrez shows us some of the crossing we saw in the earlier game today as he summons his defenders up from the back to deliver a ball from wide only to smash it 30 yards over all of their heads. Like in all of the games at this tournament so far, there is little in it in Mongomo.
Andrew Priestley:, external Two form teams going head-to-head tonight, should be interesting. I fancy the less glamorous Algeria side to win tonight.
Send us your thoughts on the game. Algeria have a decent shape, South Africa look like their built on hard work rather than organisation.
We are on #bbcafcon2015.
In comes the corner but Algeria defend it well. Rivaldo Coetzee will have to come off for South Africa, he's clutching his right knee. Siyabonga Nhlapo is on for the defender.
Bafana Bafana have grown into this and the belief is there now as Dean Furman presses quickly. They have a spring in their step. Another corner forced...
From Bournemouth to Doncaster Rovers and their midfielder Dean Furman has just smashed against the cross bar.
Rantie finds him, touch, set, 35 yards, bang. It's at the top-right hand corner and replays show Rais M'Bolhi got a vital finger to that. Some save. Some strike.
Pace aplenty again from Tokelo Rantie. He must be practicing that on the Bournemouth beaches. A ball over the top is his but the left-foot volley which follows is tame and dribbles wide.
I don't want to curse him early on, but South Africa goalkeeper Darren Keet - who plays in Belgium - looks the best in the competition based on his opening 20 minutes. He catches balls rather than punch and he now stops another stinging drive before being quick off his line as a cross drops in the middle of the area.
Bournemouth forward Tokelo Rantie gets Algerian hearts fluttering. He blows his marker away to chase a long ball and prods it around the goalkeeper but the ball runs out of play. Had Rantie gone down the referee would have had a big decision on his hands. Rantie has pace, that will offer big hope to South Africa.
For those of you wondering, Algeria manager Christian Gourcuff is the father of Lyon playmaker Yoann.
Gourcuff senior looks a little anxious on the bench but his side are bettering this and look slicker than their opponents early on. South Africa look like they will play on the break.
South Africa have conceded three free-kicks in dangerous areas already but credit to goalkeeper Darren Keet as he collects the latest delivery from Yacine Brahimi. He leapt like a salmon.
Speaking of Salmon, we will have the national dishes for these two countries later...you seem to be loving them on Twitter.
This is what winning the Africa Cup of Nations feels like...
South Africa's Phil Masinga in 1996. Those look like a size 13 (adults, not children's).
Faouzi Ghoulam of Napoli gives a 40 yard free-kick the Gareth Bale treatment with legs wide apart in his stance...he runs up..it moves around like a paper aeroplane but the keeper parries it down and collects easily. A stinger.
One-way stuff so far...
Confidence aplenty, Nabil Bentaleb sees some ball and crisply finds a team mate but South Africa get a reprieve after chasing shadows for five minutes as Carl Medjani dives into a tackle and is penalised. Get some air in your lungs guys...
You have had your say with 73 % predicting an Algeria win and just 27 % going for South Africa. Thanks for your votes.
My colleague Andy Cryer goes big and says 3-0 Algeria, I'll go 2-0.
Yacine Brahimi wants early touches for Algeria but as he dances on the ball with delicate manipulation of the ball Oupa Manyisa gets a foot in for Bafana Bafana.
It's a good start by the Desert Warriors though and Sofiane Feghouli of Valencia is prominent out wide but his deliveries don't find the mark.
Whistle in referee's mouth, he puffs...we are off...
South Africa flags are dotted around the crowd and this long national anthem draws fairly minimal flickers of emotion from players.
Bafana Bafana have won just one of their last 12 matches at the Africa Cup of Nations.
Team photos, we near the off...
