for djokovic. >> quite a big bump in the road. this is just fascinating and frankly quite extraordinary story. novak djokovic, world number one. a man who if he plays in and wins the australian open would surpass rafal nadal and roger federer with 21 grand slam titles. thought he was going to be able to play in the open because they granted him an exception from the mandate. just a handful of players. he has now arrived in australia and seems to be stuck at passport control. we know he's there because one of the players in his team has posted a picture on instagram of a couple of those team members waiting at the airport. but we understand it's been held up because visa complications. since this was granted just over 24 hours ago, there has been an absolute storm of protests in australia. whether the tournament was held was one of the most locked down cities with some 160 days spent
