The problem with 'original' is that a player who joined your club in September IRL will be in the squad in July. Becomes even more noticeable with the January window - when you started a new save with the winter update, players who joined in January are in the squad the previous July.
This above is for the real world not original
Original is the old school mode, you start with same squad as IRL, and you make transfers as you go along pending on when the date of the transfer window.
