If there is 11 on the field, at game time, you have a match on. Be prepared.
If players are missing from the field, the computer will reserve ther pace and they will magically appear at game time.
If not 11 players, you have a walkover. Be prepared, cause we are all coming over to celebrate.

If you you see a formation on the pitch, it is the current formation in play.
If the formation changes, at anytime , especially if you blink,see above.

If the above is not clear, wipe the mud
