There is just one change to the Serbia side who entertainingly drew 3-3 with Cameroon.

Juventus striker Dusan Vlahovic starts up front with Fulham's Aleksandar Mitrovic in an attacking change of formation.

Midfielder Nemanja Maksimovic is the one to drop out. Brothers Sergej and Vanja Milinkovic-Savic both start again.

Serbia XI: V Milinković-Savić, Pavlovic, Milenkovic, Veljkovic, Mitrovic, Tadic, Zivkovic, Lukic, Kostic, Vlahovic, S Milinković-Savić

As expected Brazil make wholesale changes for this one, they are already through to the last 16.

This line-up is still pretty ridiculous, though.

Ederson comes in for Alisson while Alex Telles and Dani Alves start along with Liverpool midfielder Fabinho and Manchester United's Fred.

Gabriel Jesus starts up top in place of Richarlison with Antony and Rodrygo in for Raphinha and Vinicius Junior.

Here's a quick recap of events so far in Group G.

Five-time winners Brazil have already secured their place in the World Cup knockout stages and require just a point against Cameroon to top Group G.

But who will join them in the last 16?

Any of the other three teams could still advance, with second-placed Switzerland best placed but still requiring victory over Serbia to guarantee their progress. A point would be enough for the Swiss if Cameroon fail to beat Brazil.

Serbia and Cameroon both need to win their respective games to keep alive their qualification hopes. Should both sides manage to get the win they need, Cameroon have a slight advantage with a marginally better goal difference.

Group G (19:00 GMT) - live on ITV, with commentary on BBC Sounds & website/app

• Cameroon v Brazil
• Serbia v Switzerland

Four years ago, Switzerland joined Brazil in qualifying for the last 16 of the 2018 World Cup at the expense of Serbia.

Could history be about to repeat itself? The Swiss are in pole position to join the Selecao in the knockout stages in Qatar, with Serbia needing a win against Murat Yakin’s team to stand any chance of qualification.

And then there’s Cameroon, whose remarkable comeback against Serbia on Monday kept alive their hopes of reaching the last 16. Could the Indomitable Lions upset five-time world champions Brazil?

If this World Cup has taught us anything, it is to expect the unexpected...
