Yoane Wissa is replaced by Joris Kayembe as part of a DR Congo double change.
Arthur Masuaku
WOW!!!!!
Arthur Masuaku stands over this free-kick on the left wing. Everyone is expecting a cross and he swings it in over the head of the goalkeeper. Amazing swing and dip.
Surely that's game over now.

The game has got a bit messy now.
Loads of breaks, maybe intentionally by DR Congo to slow the game down.

Cool, calm and collected from Wissa.
The power is there, the accuracy is there, and no chance for Kone.
He kept his nerve. Big moment, you need your big players and Wissa has stepped up again.
DR Congo 2-1 Guinea
What do Guinea have in response? They have only had three shots tonight.
Yoane Wissa
A very slow exaggerated run-up from Yoane Wissa but it works as he tucks his penalty into the bottom corner. The keeper guesses right but can't reach it.
DR Congo are 25 minutes from the semis.

He causes problems with his pace and power. He is galloping forward with a lot of energy and gets the wrong side of the defender.
He got across him and was smart, earning that penalty for DR Congo.
It's a clear penalty on this occasion.

He is just not warm enough there. The goal opened up for him and he just needed to keep his composure

It's DR Congo sub Silas Wamangituka who has the big impact instead. He's clipped by Julian Jeanvier in the box and it's a penalty.
