There will be a new method of ranking. PAOK is in spot #44. The difference is that a club that missed one season (for not qualifying or excluded for one year) or after a bad season will not get automatically that years points of the country. It is to prevent that the clubs that only collected points one year or two years benefit of the points collected in the other 4 years by the other clubs of their country.
An example. The coefficient of Spain is 17.799. If a club like Real Sociedad collected in one of the past 5 years 18.500 they will have 18.500 for the ranking. In the old system the would had about 32.700 (18.500 points the collected themselves and 4 x 3.200 as the avarage of the years the didn't complete). Earning them a pot 2 draw in GS, while now they will be pot 3 or 4.

There will be also a 10 year ranking for the distribution of the revenue. We are in spot #60. Sounds fair as we are/were always around that spot:
