What a difference a week can make in football. Just take a look at Arsenal's last seven days: two losses, a minor fan revolt, national media attention drawn to said revolt, and, perhaps most importantly, a big drop in the latest edition of the European Club Rankings.
The rankings are now season-long in their measurement of clubs. Previous editions of our rankings only took recent form into account (spanning four to six weeks), but this version tracks teams throughout 2016-17.
Teams that have lost the fewest games in all competitions naturally rank higher, and Champions League form and presence is used as a tiebreaker for those with similar records.
