Don't use math. They won't understand. Obviously Murray is the bigger server and returner in their match-up, so if he's playing well there isn't much Djokovic can do. The match is due to Andy's mentality and focus, which is still quite up down.
These murraytards are getting out of hand.
Djokovic's best is still > than Murray's best. The problem is that Djokovic is rarely at his best when playing Murray, of course because of the match up or because Murray can neutralise his weapons better. But in the rare occasions I have seen both of them at their best, like Rome last year, you still knew Djokovic would win. He even wins those he doesn't play at his best, like AO or yesterday. That doesn't mean Murray has nothing to do with the outcome of these matches. He most often than not forces Novak to play worse than his best, which is a triumph in itself. But when he cannot achieve that, because you know Nole ALWAYS steps it up later, that's when problems begin for him and he knows it. Novak has an attacking mentality that Murray doesn't have and he always tries to attack first.
