 It's a big ask for Djokovic, Isaac, because he comes here in the unlikely position of actually being an underdog this time. Like you said, he had that knee injury at the French Open. He's since had surgery. He's here after having had surgery three weeks ago. And a knee injury is a big thing, isn't it? And to reach that final, he's going to need to play six matches, potentially of five sets, before he even gets to a final. So it'll be really interesting to see how that knee does hold up.
