France and Switzerland are the first teams to qualify for the knockout stage at Euro 2016.
Here is a look at what England, Wales, Slovakia and Russia need to do in their final group game to join them in the last 16.
Slovakia (3 points) vs England (4)
England need a draw to qualify and a win to top Group B.
Slovakia will progress with a win. They will finish as runners-up with a draw, provided that Russia beat Wales.
Slovakia will finish bottom of the group - and exit the tournament - if they lose and Russia win.
Russia (1) vs Wales (3)
Wales will qualify with a victory. If they draw and Slovakia fail to beat England, they will also be through.
If they draw and England lose, both teams will be on four points. But Wales will be third behind the Three Lions due to an inferior head-to-head record.
Wales will then need to hope that four points are enough to place them among the four best third-placed teams. Those four teams will progress alongside the winners and runners-up of each of the six groups.
Russia must win or they will be eliminated. A victory could take them up to second in the group if England lose.
With Russia and England drawing their clash, no team holds the head-to-head advantage. As such, the team with the better overall goal difference will go through. England's goal difference now is +1, while Russia's is -1. If the teams are still level, the team who scored more goals will progress. England have three goals so far; the Russians two. If that is not enough to separate the teams, disciplinary rankings will be the next determining factor followed by the coefficient rankings. Should it get that far, England would have the advantage.
