So who needs what?
By Dean Bilton
Brazil: Already through. Highly unlikely they'd drop to second even with a loss, but a point would ensure top spot.
Cameroon: Need to beat Brazil, preferably by a couple of goals. Then it comes down to the other game, where a draw or Serbia win would probably be better.
Serbia: Need to beat Switzerland and hope Cameroon don't beat Brazil beat Cameroon. If Cameroon get a result, Serbia would need a decent goal difference boost to get ahead of them.
Switzerland: A point against Serbia would be enough, provided Cameroon don't beat Brazil.
Neymar is in the building

But will he play again in this tournament? And if he doesn't, can Brazil still win it? Those are the big questions surrounding the Selecao as they look to tune up for the knockout stages.
Brazil ring the changes
By Dean Bilton
Some hope for Cameroon? Concern for Swizterland and Serbia? With qualification already secured, Brazil have made NINE changes for this game against Cameroon.
Coming out are Alisson, Marquinhos, Thiago Silva, Alex Sandro, Casemiro, Lucas Paqueta, Vinicius Jr, Richarlison and Raphinha.
Coming in for them... well, basically just check out the full starting team above. It' s still a pretty damn strong second XI.
The action so far today
By Dean Bilton
Drama in Group H! Uruguay beat Ghana 2-0 fairly comfortably, and looked to be on track for progression until Souh Korea found a shock late winner against Portugal to turn the group on its head.
That win sent the South Koreans through and dumped Uruguay out, hence Luis Suarez's reaction above.
Final scores and table:
South Korea 2-1 Portugal
Ghana 0-2 Uruguay
The grand group stage conclusion
By Dean Bilton
Morning all! There are just two games left in the group stages of the 2022 World Cup, and they will be used to decide the final make up of Group G.
We've got Cameroon playing Brazil needing a win to sneak into second spot, while a win would most likely be enough for Serbia to advance over Switzerland, who probably only need a point themselves.
The drama of the last few days at this tournament has been quite something, so lets hope this morning is no different.
