They are coming forward at any opportunity now.
Guinea are on the back foot after taking the lead and they are going to have to keep composed because DR Congo are really going to come for it.
DR Congo 0-1 Guinea
No immediate response from DR Congo to that goal. They'll be wishing they'd scored one of their early chances.

He kept his nerve there. It is a long wait.
It's controversial and Bayo has had to keep calm there and it was a lot of pressure.
He deserves a lot of credit. He was so calm under pressure. He kept his nerve.
DR Congo 0-1 Guinea
Mohamed Bayo scored a 98th-minute winner in the last 16 against Equatorial Guinea.
The 25-year-old, on loan at Le Havre from Lille, is having a great time.
Mohamed Bayo
After a long old wait to take it, Mohamed Bayo sends the keeper the wrong way and places his spot-kick just right of centre.
Guinea lead.

I am very surprised with that one. I thought Chancel Mbemba was shepherding it our and putting his body in the way, like a good defender would.
Nothing is really standing out and it looks soft to me.
DR Congo 0-0 Guinea
The referee puts the ball on the spot so VAR must not be interfering. Was that a fair shoulder barge? DR Congo certainly think so.
DR Congo 0-0 Guinea
Chancel Mbemba barges Mohamed Bayo over in the box and the referee points to the spot.
Huge chance for Guinea here.
DR Congo 0-0 Guinea
DR Congo have won Afcon twice before, back when they were called Zaire, in 1968 and 1974.
Guinea have never won it, finishing as runners-up in 1976.

Again, he will be scratching his head. There is so much space in that box.
Moutoussamy has a lot of time there. He could have taken a touch. They blocked it but he could easily have punished Guinea there.
DR Congo 0-0 Guinea
Theo Bongonda drags a shot well wide from long range for DR Congo. They have had most of the opportunities so far.
DR Congo 0-0 Guinea
Two fine dummies find DR Congo's Samuel Moutoussamy in space on the edge of the box but his first-time effort is blocked by defender Mouctar Diakhaby.
DR Congo 0-0 Guinea
Guinea's Morgan Guilavogui catches Charles Pickel. He's given a warning by the ref but no card for now.

Both sides always have this rivalry where you respect each other. We have had some big games in the past but not as much as this.
This tournament has thrown up a lot of shocks and both teams will back themselves to go all the way. Hopefully we keep the entertainment up.
DR Congo 0-0 Guinea
A slight bit of a lull now after an end-to-end start.
DR Congo 0-0 Guinea
Meschak Elia flies down the right for DR Congo but his cross is dealt with by Ibrahim Kone.

I think Wissa will probably be a bit upset with himself there. It bounced nicely but it was a bit of confusion in the box.
You can see that the goalkeeper is not happy. You have to take responsibility there as a defender.
He has his pocket picked by Wissa and he should score. DR Congo should be in front.
DR Congo 0-0 Guinea
Big opportunity for DR Congo as Yoane Wissa pokes a shot wide. Guinea get in a total mess about who's dealing with a throw-in and it lands to Wissa in space, who should finish.
Keeper Ibrahim Kone is furious with his defenders.

Chancel Mbemba comes across and tries to head it and he doesn't really know much about it.
It would be harsh.
