Welcome to the opening edition of the 2018-19 European Club Rankings, your definitive source for how the continent's best teams are performing on a weekly basis.
Once the season kicks off, this will turn into a rolling, performance-based list, but this version is a more simplistic, on-paper assessment of football's powerhouses.
Put simply, Europe's top 20 sides have been ranked based on how good they are before a ball is kicked. We take into account squad strength, transfer-window work, managerial appointments and the likelihood of silverware in measuring them.
You can consider this list somewhat predictive, too.
