Tennis journalist Steve Flink believes that Medvedev's slow demise started with the Australian Open as the Russian never looked the same after the event.
Medvedev found himself on the wrong side of the net for an amazing comeback of Rafael Nadal that will be forever remembered. He had his second grand slam in hand leading him convincingly at the Australian Open but it all changed. Nadal battled and battled and eventually, he prevailed.
It's been a downward trend ever since ever Flink called it a golden opportunity:
"I think it was a golden missed opportunity for Medevedev. I don't think he's ever been quite the same since."
The problematic part is that Medvedev failed to overcome it since then despite plenty of time passing:
"He's had plenty of time, I think to put the ship back in order."
