When the euro's expand to 24, are UEFA likely to stick with 9 groups for qualifiying? For France '16 if they are keeping 9 groups, I'd imagine they might go with:
9 group winners qualifying automatically.
9 runners-up qualifying automatically.
1 best third placed team.
4 play-off winners from the remaining 8 third placed teams
1 Host - France.
24 countries.
