Sibusiso Vilakazi has Affonso up in support, but looks to go for goal himself. Wrong decision — the shot is blocked! There will be three minutes of stoppage time.
At the other end, the other Vilakazi has a shot, AmaZulu's Nhlanhla Vilakazi. Onyango tips it over the target — he might not even have needed to, but wasn't taking chances.
FULL-TIME: MAMELODI SUNDOWNS 5-0 AMAZULU. A first half goal from Meza was complemented by two in the second half from Sirino and one from Affonso, with a Booysen own goal also adding to Sundowns' tally. A totally dominant display to put them into the QFs.
GOAL, SUNDOWNS, AFFONSO! 5-0: Morena crosses in from the right and Affonso heads home from close range! Boshoff seemingly wasn't anticipating the contact and was looking to punch the cross away. Perhaps he could have done better.
De Jong is on for AmaZulu, having replaced Ntuli a few minutes ago.
Meanwhile, Darpoh picks up a yellow card as Usuthu give away the free-kick.
Vilakazi gets the ball in from the right, looking to pick out Affonso. However, AmaZulu deal with the danger.

Coetzee comes on for Sundowns in place of Kekana, with Mosimane perhaps protecting his captain ahead of a crucial week.
GOAL, SUNDOWNS, SIRINO! 4-0: Perfectly-placed shot from Sirino! The ball is taken off Affonso in the box, but it rolls out to Zwane, who passes back to Sirino, who picks his spot and fires home for his second goal!
Speaking of Vilakazi, here comes Sibusiso Vilakazi for Mamelodi Sundowns. He comes on in place of Jali, who looks as if he might have picked up an injury.
Vilakazi goes for goal from the edge of the box for AmaZulu, but he fails to really get over the ball as he pulls the trigger and his effort goes well off target.
Maduna looks to play Majoro in behind, but it's not the right ball and he can't get to it first.
Meza is off, replaced by Affonso! It will be interesting to see how the new man at Sundowns takes to this competition.
A long-range shot from AmaZulu goes well over the target. Onyango restarts play with a goal-kick. Affonso gets a good cross in at the other end for Zwane, but he can't quite turn it into the net.
GOAL, SUNDOWNS, SIRINO (P)! 3-0: Boshoff goes the right way, but he can't keep out a powerful SIrino strike! Replays show perhaps Morena made the most of the contact from Gumede, but he arguably could have had a penalty earlier!
Morena goes down inside the box. This time, Thando Ndzandzeka awards a penalty! Mbongeni Gumede is the guilty party. Sirino can all but wrap the game up.
Langerman's ball in finds Morena in the box, but it's taken off him. AmaZulu look to counter. Onyango races out again to cut out the attack, heading the ball away this time. The offside flag is up against Ntuli in any case.
AmaZulu go forward again, with Sithebe getting a shot at goal, but he's off balance and it goes wide of the target.
The substitutions appear to have vitalised AmaZulu. They go for the ball over the top, which nearly finds Ntuli. Onyango does well again as he races out to scramble it away!

Sirino looks for the head of Lebusa, but he can't get a clean connection and AmaZulu restart with a goal-kick.
OWN GOAL, BOOYSEN! 2-0 SUNDOWNS! Jali floats the ball through the air and Boshoff comes out. Booysen gets on the end of it and heads back, but over his onrushing goalkeeper and into the net! Own goal on debut.
Kekana is on the end of another heavy challenge as Ntuli kicks him. Shortly afterwards, Sikhakhane clatters into Meza. AmaZulu need to keep their heads. Sundowns have a free-kick out wide.
Vilakazi has been handed a yellow card for a late tackle on Kekana, with referee Ndzandzeka coming back having initially allowed the game to continue. That's the game's first booking.
Langerman crosses from Sundowns' left, but Boshoff holds on. He's quick to release the ball, looking to get his team on the front foot.
AmaZulu have started the second half with an attacking mindset, as they needed to do. Karuru goes for goal with his left, but the shot is blocked.

The ball finds Ngcongca from the corner and he lines up a shot, but it's taken off him just as he pulls the trigger.
We're into two minutes of stoppage time at the end of the half. Sundowns have had more chances, but AmaZulu have remained resolute.
GOAL, SUNDOWNS, MEZA! 1-0: Morena plays Zwane through and he passes across goal for Meza. The flag stays down and he slots in! Boshoff looks towards the touchline, calling for offside, but the goal stands!
HALF-TIME: MAMELODI SUNDOWNS 1-0 AMAZULU. That's the last kick of the half! Meza has looked lively for Sundowns throughout and he sends them into the break in front in Atteridgeville. AmaZulu soaked up pressure, but eventually cracked.
Lovely bit of skill from Sirino, but the pass inside for Morena is a poor one and gets intercepted. Sundowns come forward again and Kekana lines up a long-range shot, but that's blocked. Zwane then wins Sundowns a corner.
Sithebe finds Karuru out wide. He passes back inside to Sithebe, whose shot is blocked. Vilakazi floats the ball in, looking for Ntuli. Madisha heads clear.
Meza has a long-range shot at goal, but he drags it wide of the target.
Meza, at the back post, tees up Zwane for the shot. Mshishi takes too long to shoot and Usuthu scramble the ball away. Not the first time Sundowns have made that mistake.
Langerman's cross is beaten away by Boshoff towards Gumede. AmaZulu are under siege, but they're fending off everything that comes their way.
Kekana goes for goal from long range, but it's straight down Boshoff's throat and the goalkeeper holds on well.
Wonderful hold-up play from Ntuli, who gets the ball and fends off Madisha, playing the return ball for Karuru. However, the Zimbabwean doesn't catch his shot sweetly and Sundowns survive.
Meza is played through by Sirino, but flagged for offside. It looked a tight call, but the replay suggests it was probably the right one.
Sithebe's cross is caught by Onyango, who initiates the Sundowns counter, but AmaZulu are back in numbers and they manage to frustrate the Brazilians.
Zwane looks for the ball over the top for Meza, who looks to beat Xoki to the ball. However, the AmaZulu captain manages to put it behind. The ensuing passage of play sees Madisha unsuccessfully go for an overhead acrobatic shot.
Langerman is released with Kekana the creator again. However, he takes too long to pull the trigger. Boshoff rushes out to his feet and takes the ball off him.
Jali lunges in on Karuru and gives away the free-kick. Perhaps he's fortunate not to be yellow-carded for that late tackle.
It's time for a water break under the searing Atteridgeville sun. The temperature is 34 degrees celcius.
Ntuli doesn't have enough support up with him, so he's dispossessed. Sundowns go for the ball over the top aimed towards Zwane, but Mshishi is flagged offside. Tight call, that.
Morena is released by a fantastic Kekana long ball. However, he fails to control it and the ball goes behind. Sundowns get the corner. From there, Ngcongca forces Boshoff into a save, but he holds on.
Chance for Sirino, but he looks to tee up Kekana instead of going for goal himself. The pass is overhit and Boshoff holds on!
Meza holds the ball up well and tees up Morena inside the box. He goes down. Sundowns appeal for a penalty. Not given! Replays show Booysen is a very lucky man not to have been penalised there.
Darpoh puts the tackle in on Morena just as he's about to shoot from just outside the box. As a result, the strike fizzes wide of the target. Usuthu get the goal-kick.
Zwane tees up Kekana for the shot, which misses the target, but the captain was offside anyway — no debate there. Definitely the correct call from the assistant referee.
At the other end, Sithebe lines up a shot, but fires wide of the target.
Sundowns have the ball in the back of the net, but the flag is up for offside and it's disallowed! Not sure whether the ball to Morena or his pass inside for the finish was what prompted the flag to go up. That one needs further scrutiny.
Sirino looks to link up with Meza, but Boshoff rushes out and intercepts the ball. Alert goalkeeping.
Sithebe's corner is cleared by Langerman at the near post and Sundowns look to counter. However, AmaZulu get the ball back as Jali looks to pick out Sirino. It's Vilakazi who tidies up for Usuthu.
Meza pushes Darpoh, who goes down and gets AmaZulu the free-kick, although perhaps he could have stayed on his feet. It's taken short and worked towards Booysen, who gets a shot at goal. Decent strike, but not quite on target.
KICK-OFF! Ndzandzeka blows his whistle and Usuthu get the game underway.
Hello and welcome to our live coverage of the Telkom Knockout last 16 clash between Mamelodi Sundowns and AmaZulu at the Lucas Moripe Stadium.
Masandawana have dominated the league in recent seasons, but they've not had it all their own way in cups. They have only ever won this trophy three times — the last being in 2015.
AmaZulu got the season off to a poor start, leading to their coach, Cavin Johnson, being shown the door. Jozef Vukusic recently led Usuthu to their first league win of the season against Cape Town City. Can his men kick on?
MAMELODI SUNDOWNS XI: Onyango, Ngcongca, Madisha, Lebusa, Langerman, Zwane, Jali, Kekana (c), Morena, Sirino, Meza. SUBS: Mweene, Vilakazi, Coetzee, Lakay, Mahlambi, Maboe, Affonso.
AMAZULU STARTING XI: Boshoff, Sikhakhane, M. Gumede, Xoki (c), Booysen, Vilakazi, Darpoh, Sithebe, Ncube, Karuru, Ntuli. SUBS: Mbatha, P. Gumede, Khumalo, Morton, Maduna, de Jong, Majoro.
Key talking points from those teamsheets: Jali starts in midfield for Sundowns and has a chance to prove himself. He's blown hot and cold since signing for Sundowns last year. Boshoff starts in goal for Usuthu, as does new defender Booysen.
Nearly all set for kick-off. Thando Ndzandzeka is today's referee.
