Not sure why it's kicking off but a yellow card has been shown to a Serbian substitute after the entire dugout began spilling onto the pitch in frustration and there's stil some arguing between players on the pitch. The referee comes across, blowing his whistle aggressively and it quickly dies down.

Half of the Serbia substitutes are now on the pitch, remonstrating with the referee over Schar's challenge on Mitrovic.

Pedrag Rajkovic is shown a yellow card.

Checks out, thanks Rob!

Really good sliding tackle by Enzo Ebosse inside the box to deny Everton Ribeiro. He had to get that one right and did.

Serbia want a penalty as Fabian Schar catches Aleksandar Mitrovic with a flailing arm.

The striker goes to ground rather theatrically though. The Serbia bench aren't happy, but the referee isn't interested.

It is a change for each side as Cameroon send on Karl Toko-Ekambi for Bryan Mbuemo.

For Brazil, Gabriel Jesus - who has been quiet - is replaced by Pedro.

Ricardo Rodriguez plays a dreadful throw into the feet of Dusan Tadic and Serbia work the ball out to the left-hand side.

Filip Kostic takes a touch before sending a low cross towards the six yard area, but Gregor Kobel gathers at the second attempt.

A let-off for Switzerland and Rodriguez.

Cameroon are preparing some changes. They need them because the momentum is firmly with Brazil.

Switzerland only half clear a hopeful ball into the penalty area and Dusan Tadic slices over, under pressure from several Swiss defenders.

Serbia are enjoying a good spell of pressure now.

Just under 30 minutes to go.

Switzerland are heading through as things stand. Serbia need to turn things around to qualify. Cameroon's best chance of reaching the last 16 relies on them beating Brazil and a draw at Stadium 974.

Brazil are lacking a cutting edge so far, and that is shown here by the lack of successful dribbles from wingers Antony (19) and Rodrygo (21).

They have only completed two successful dribbles between them, far away from goal.

Ruben Vargas barges into Vanja Milinkovic-Savic, who gets to his feet before giving the Switzerland man an earful.

Much ado about nothing.

The Cameroon keeper Epassy crashes his head against the post. That's awful. It's good to see him sitting up, he's very brave, but you can't tell me he won't get a concussion from that. The medical team have obviously said he's alright, but he's hammered his head against that post.

Devis Epassy does well to get his hand to a tricky corner but then falls awkwardly back onto the post. The whistle is blown so he can receive some treatment.

Some concerned faces on the Cameroon bench but eventually he is OK to continue. That will be a relief as he has made some fine saves.

Nicks: This Serbia defense makes Shaquiri look like Messi, shocking defending

Tobias: As it stands, no team would have won all three of their group games. Has this ever happened before?

Anybody got an answer for Tobias?

Almost a fourth for Switzerland but Breel Embolo scoops over from point-blank range.

It wouldn't have counted anyway - the linesman's flag was up.

The referee now brandishes a yellow card in the direction of Strahinja Pavlovic, who will be suspended for Serbia's last 16 game if they make it through.

The defender can't believe it.

Good break by Gabriel Martinelli down the left. He gets into the box, cuts on his right foot and smashes a shot goalwards that Devis Epassy does well to push over.

Following the corner, Eder Militao's shot through a crowded box is pushed onto the post by Epassy.

Brazil are pushing now.
