It's a daft comparison because the level of competitors is lower so it's all relative. Based on your logic, the A-League is not the same as La Liga or other league competitions, and frankly nowhere near as difficult to succeed in.And the ACL successes. It's nice to have that, sure. But don't look too much into the ACL- many clubs don't take it seriously, it's not the same as the European CL or other cup competitions, and frankly nowhere near as difficult to succeed in.
Perhaps we shouldn't look too much into any domestic success either?
