Can we stop praising Medvedev alone? Let me take you back to the Olympics. Djokovic was invincible..absolutely invincible. Zverev landed the body blow and Djokovic unravelled.
Zverev landed the second blow in the semis of the USO exhausting him mentally and physically. By the time he met Med, Djokovic was already spent.
Sure, Med played great. But, a fully charged Djokovic would've been a nightmare for him. A close match that could've gone either way.
