Here is a look at what Spain, Croatia, Turkey and the Czech Republic need to do in their final group game to progress into the last 16.
Czech (1 point) vs Turkey (0)
A must-win game for both sides. The Czechs need the three points and have to hope that Spain beat Croatia to have a chance of finishing second in the group.
Even if they finish third, four points would put them in a strong position to qualify as one of the four best third-placed sides. A draw would see them also finish third but in a much weaker position.
For Turkey, even victory may not be enough. A win would see them finish third and on three points but given their current goal difference of -4, their chances of entering the knockout round are slim.
Croatia (4) vs Spain (6)
A draw would suit both teams and see them qualify for the next round in their current positions. Spain have already booked their spot and a point will be enough to see them finish as group winners.
Defeat would see the defending champions fall to second and leapfrogged by the Croats. Should Croatia lose, they face a nervous wait to see if they will drop to third, though that is dependent on the Czech Republic beating Turkey and then overtaking them based on goal difference, then goals scored, then fair play record, then Uefa coefficient ranking.
Croatia have scored three goals, conceded two, for a goal difference of plus 1. The Czechs have scored two, conceded three for a goal difference of minus 1.
Both teams drew 2-2.
