Did some more research on the subject ...
For reaching the EL group stage we are getting the following:
€ 2,920,000 - for making the group stage of EL
€ 2,777,130 - coefficient payment (based on 5-year coefficient in UEFA standings)
€ 2,000,000 (minimum) - 5,692,130 (maximum) - market pool (based on how many Greek teams make the group stage
So far we have € 7,697,130 guaranteed
If we qualify to the CL playoff round (and lose) we will receive an additional € 5,000,000
In group stage we will also receive € 570,000 for each win and € 190,000 for each tie. If we win the group we will get extra € 1,000,000. If we finish 2nd we will get € 500,000
If by any miracle we make the CL group stage we will make a lot of money. We will revisit this if it happens.
