I guess we won't know that until May 2023. I always laugh at the bandwagon fans that jump on and off based on couple of games during the summer heat.
To answer your question, it looks like Panathinaikos, Aris and AEK will be improved. I don't see Olympiakos being better, but we know they have other ways to achieve their goals. I don't think we can contend for the title, but 2nd place is achievable. After that 3rd to 5th place does not make much difference as it gives you the same price, which is ticket to Conference League.
