With the European Championship format switched to 24 teams, it has made things tricky in figuring out the last-16 nations. The top two from each of the six groups qualify automatically with four more teams progressing.
Four of the best third-place teams will keep their hopes alive with two being eliminated. Also confirmed to be heading to the exit door will be the teams that finish bottom of their groups.
With the group stage games ending on Wednesday, we take a look at the format and the teams in the running for the third place spots.
To figure out which teams go ahead, all the third place teams are placed in a separate group to determine their overall standings among each other.
