This game shows how far away we still are from the absolute top European teams. And to think people here are always so sure we would rape Real/Barca/Bayern . We are not there yet, I hope it's clear now.
You summed it up nicely, quarter-finals of Cl is pretty decent achievement , 2 or 3 quality signings and we can hope for a better result next year, this team as it is now is simply not good enough for top European football.
