That's correct - All 11 players must come from those 6 teams and you can choose a maximum of 5 players from each team.

The following week, there are 4 games at 3 o'clock so you'll be able to choose from 8 teams.

I think that some of the rules will need tweaking as we go along - especially with some of the points scoring. It might also be that in the future, I'll allow people to choose from a set of pre-defined formations so that we get some more variety. Although if I do, then I'll need to change the name of the game!
