Exactly this. We're not a top 5 club of the last 20 years because of the lack of a CL title. Which sucks. Because we really should be.
Regardless, if I had to pick my poison, I'd rather be featuring in the biggest European matches each year in the SFs and Finals,
than be some scrub team always knocked out in the early stages. One day we'll win. We have to. I'd rather not contemplate losing another 5 straight finals over the next 20-30 years.
Faith. Gotta have it. And the domestic success will take the edge of that hunger until it's finally sated.
