Hi Swerdis! It's very nice that you follow a team from the lower leagues of your country! I often watch matches from 3 clubs from the lower leagues of my country , but the main reason is that I have some connection with the places they belong ( and all three share the same name with the places they belong , they are practically the local clubs of these towns ) . First one is Kallithea .
Kallithea is a suburb of Athens , and it is the place where I live. Second one is Kalamata . Kalamata is the town my mother has been born , it's a town in southern Peloponnese and we also own a house in a small village near it. Third one is Petralona . Petralona is a neighbor suburb of Athens ( you can easily go there from my home by feet ) . Also a very popular football journalist of my country , supports them ( he lives there too ) , and he often analyses their matches .
As for what you are saying about the Champions League having always the same teams performing well , that is correct , and the main reason are the insane costs that you need to pay in the transfer market , to have lots of world class players on your team. Also the huge revenue that the teams which participate in Champions League enjoy , can create large disparities in their national leagues , compared to the teams that they don't have that privilence . That is not so visible in the large countries with popular leagues ( like Germany , England or Spain ) , because they broadcast their leagues to many other countries and they get a lot of revenue , that helps them imo to balance things out a little bit.
For example here in Greece , if you have subscribed to the tv stations me and my father have subscribed , you can easily watch many of the Bundesliga matches . And if you miss a match , you have even the option to watch it later or one of the following days " on demand" on your tablet.
Smaller counties with smaller leagues that also have one of their teams participating in the Champions League , have the potential for larger disparity problems imo . For example for many of the previous years , Olympiakos here in Greece had a very large edge compared to their main competitors ( like AEK or PAOK ) , but at the last 2-3 years they have lost that edge , mainly due to the bad habit the president of the club has , to sell lots of the good players of the club .
