Breel Embolo
This game just keeps on giving!
It's a wonderfully worked goal too as Djibril Sow feeds Silvan Widmer on the right, and the defender's low cross is slotted home by Breel Embolo.
What a first half this has been...

I can't wait to see a side play Brazil and go toe-to-toe with them because they are breezing through this game.
Serbia 2-1 Switzerland
Key to Serbia's turnaround has been Dusan Tadic's performance.
He has been a real threat down the left, particularly since Switzerland's opener, laying on the cross for Mitrovic to level.
Here is his heatmap; he is consistently finding dangerous positions.

Dusan Vlahovic has scored 10 goals in 19 appearances for Serbia, including seven goals in 10 starts.

Just seen Cameroon legend Samuel Eto'o in the stands. He boldly predicted his team to win the World Cup before the tournament got under way, backing them to beat Morocco in the final.
The Serbia goal does keep that dream alive but Cameroon need to win as well tonight.

It's been a really good game this and there's another chance for the Swiss.
Serbia 2-1 Switzerland
This game continues to ebb and flow at breakneck speed.
Strahinja Pavlovic produces a tremendous block to prevent Ruben Vargas - who was booked a few moments ago - from firing Switzerland level again. The Serbia defender celebrates by clenching a fist in the direction of the Serbia fans.
Serbia are heading through as things stand.
Switzerland will be joining Brazil in the last 16 if they net a leveller. Should Cameroon take the lead, they'll be up to second.
What a World Cup.

Antony cuts inside from the right before bending a shot at goal but it is too close to Cameroon goalkeeper Devis Epassy.
There's a pause in play right now with Collins Fai needing some treatment on the pitch.

Another brilliant finish by Dusan Vlahovic. He also put his finger to his lips, gesturing "shh", mirroring Xherdan Shaqiri's earlier celebration for Switzerland. This game is delivering on all fronts so far.

I suppose we can't have drama in every game as this one is a little bit flat at the moment.
Plenty of time for things to liven up.
Dusan Vlahovic
Turnaround complete!
Serbia surge forward again and Dusan Tadic picks out Dusan Vlahovic inside the area. Remo Freuler has a chance to clear the danger but fails to make proper contact with the ball, allowing Vlahovic to steer a low shot past Gregor Kobel and into the far corner.
The Serbia fans go wild.

That was an awful free-kick from Dani Alves. No conviction. Blimey, he went really safe with that.

Anon: Shaqiri now has five World Cup goals in his career so far, Rooney had one...

Aleksandar Mitrovic almost steals in at the far post but the ball goes out of play before the striker can get a decisive touch.

Andy Cryer
BBC Sport in Qatar
Cameroon have a real chance here but they haven't really laid a glove on Brazil yet.
You get the feeling it is a matter of time before this sea of Brazilian yellow is sent into a frenzy...
Cameroon 0-0 Brazil
No.
Captain Dani Alves sends it over the bar.
Cameroon 0-0 Brazil
Collins Fai is the latest Cameroon player to go in the book as he brings down Antony as the Brazil man charges forward. It is another free kick in a decent position for Brazil. Will they make this one count?
Cameroon 0-0 Brazil

Brazil boss Tite doesn't look overly happy with his team. He's going irate down there and is talking to Fred among others.
