South Africa have to score or Nigeria are through.
William Troost-Ekong (Nigeria, scores)
Smashes it in. His second penalty of the night.
Nigeria 2-1 up after three penalties each.
Efan Ekoku
Former Nigeria striker on BBC Two
Ola Aina is usually such a good striker of the ball, I would not have expected him to have blasted it over.
That's what tension can do to you.
Evidence Makgopa (South Africa, saved)
A very similar effort to South Africa's first and it's saved.
Ola Aina (Nigeria, over the bar)
Oh no, he skies it after the keeper goes the other way.

I'm an idiot. Don't listen to me. Well done Terem Moffi!.
Ross, Highlands
Confident penalty from Moffi
Victor, Accra
Mihlali Mayambela (South Africa)
Good penalty. Keeper guesses right but the kick is beyond his dive.
Kenneth Omeruo
Nonchalant run-up from the late sub, who slots into the bottom corner. Keeper doesn't even dive.
Tebono Mokoena (South Africa, saved)
Not a great penalty, not in the corner at all, and the keeper gets down low to save.
Nigeria 1-1 South Africa
Efan Ekoku
Former Nigeria striker on BBC Two
Nice and cool from Moffi.
I'm pleased for him. To step up and take the first penalty and dispatch it is huge.
Terem Moffi
Low and straight down the middle after the goalkeeper dives.
Nigeria to go first in the shootout.
Nigeria 1-1 South Africa
Kolo Toure
Former Ivory Coast & Arsenal defender on BBC Two
This is the only moment in football that you feel alone.
You know when you have the ball in your hand ready to take it, your family, friends, the whole country are watching you.
Nigeria 1-1 South Africa
This was the drama in the last few minutes of normal time. Nigeria thought they had scored a second, instead they had conceded a penalty, which South Africa scored.
Nigeria 1-1 South Africa
Ronwen Williams saved four penalties in the 2-1 shootout win over Cape Verde in the quarter-finals. Will he be the hero again?
William Troost-Ekong has already beaten him from the spot today.

Nigeria v South Africa: Watching at a lively bar in Cotonou. This heavily pro-Nigeria crowd will melt down if we see a repeat of Williams' shootout heroics.
Stefan in Benin
Nigeria 1-1 South Africa
Nigeria 1-1 South Africa
We're into the 121st minute. Any goal now is surely a winner. If not, it's penalties for a place in the final.
Nigeria 1-1 South Africa

Victor Osimhen knew that VAR check from the referee was coming before everyone else in the stadium.
The recently-substituted striker obviously saw something on a screen in the dugout and then raced out to the touchline, waving his arms and drawing the imaginary TV screen in the air.
None of the South Africans blamed Grant Kekana for the foul on Terem Moffi.
The defender received hugs from most of his team-mates on the field before also being consoled by head coach Hugo Broos.
