By my calculation, based on the post above, we will need to start at least 1 regular starter (at CB) and can start as many as 7: Villa, Harrison, Minimax, Ring, Callens, White, Johnson (note that doesn't count Pirlo). The other 4 usual starters (Matarrita, Wallace, Chanot and Herrera) are not available.
I think we sit one of Callens and White and maybe one of Villa and Harrison. We could go entirely without starters in the midfield, but I suspect we will play our two starters there.
Remember that because of depth issues created by international duty, injuries and roster restrictions, at least 5 and probably all 7 of the available starters will at least be in the 18 and available to play.
