for whatever reason i'll bite: how so?
At 2020 AO Nadal lost 76 46 76 76 to Thiem, a higher quality than Djokovic-Thiem.....because Nadal took Thiem's best shots, so Djokovic faced a weakened version in the Final.
Nadal made the 2019 AO Final even though he had ankle surgery at the end of 2018 and wasn't allowed to practice his defense/retrieving in January.
Remember in Nadal's first 6 matches at the 2019 AO people said "why is he attacking so much" and "looks like he's got a new playing style".....ah he was attacking because he couldn't defend.
And when you play Djokovic you have to defend before you can attack.....you have to work the point.
"....because of the things that happened to me in terms of surgery, then what happened in Abu Dhabi, I was not able to work that much the defensive game. I worked a lot on the offensive game, but not that much on the defensive game.
To play against a player like him, playing the way he played tonight, I needed that defensive game to finally have the chance to be offensive, no?"
