The group stages come to an end today with action from groups G & H. So far, 12 teams have qualified and four more will be decided on Friday.
In group H, Portugal has already secured their place in the knockout round but will want to make sure of the top spot when they face South Korea.
Ghana and Uruguay lock horns again in the World Cup after their last meeting in 2010 saw the South American side progress to the semi-finals after a shootout victory.
Group G has been dominated by Brazil who is yet to concede a shot on target. Tite’s men will once again be without Neymar when they face a Cameroon side who need to win to stand a chance.
In the other game, Switzerland and Serbia are involved in a shootout for a place in the round of 16 with the winner progressing.
