The standard of the league is a concern but its nit Asteras' fault.
Asteras (yes I'm biased) have earnt their place in the GSL and Europe and are a force in Greece. Tell Besiktas and Partizan Belgrade what they think of Asteras. This year the club has a shocking injury crisis yet they are still competitive. They also have Greek players that are improving. Giannou, Fountas and Kourbelis are on the periphery of the Ethniki and are not far off from being selected. They don't need to be playing for a 1990s Era Big 3 club to prove that they are good enough.
The fact that that they come from a small town is a strength to the GSL. Do we need 10 clubs from Athens?
Akratitos, Apollon Athinon, Athinaikos, Panionios, Egaleo, Kalithea, Thrasyvoulos etc only ever make up the numbers. They aren't improving the standard for which you are continually jumping up about.
Historical clubs like AEK returning are helping the standard of the league. It's only a matter of time before ARIS and Larissa and potentially OFI get themselves sorted and return however there is a place for Xanthi and Asteras. If they are getting results then their place in the league is justified.
So it's a mute point. Stop banging on about it.
