17/18 was no vintage either, despite the CL. We've been in decline, getting older and we've kept fecking up in the market. Now with Covid, it's probably going to be another couple seasons before we can go back to the level of 2010-1017
17/18 was no vintage and clearly declining indeed but still able to get wins away vs PSG, Juventus and Bayern and beat Liverpool in the final which is something many teams in their prime, not to mention 19/20 Madrid, could only dream of.
Yesterday half that quality had gone, the other half was still there but two years older as you said. All in all the feeling one or two frightening players to scare the rival were missing was always present.
The only hope for Madrid is to promote the likes of Rodrygo, Vinicius, Valverde, Odeegard, Kubo, Reinier, Miguel Gutierrez etc, save money for the world class available in Europe and hope for the best. I don't even think we can expect to reach that kind of quality (2010-2017) anytime soon.
