Australian Open I Novak Djokovic masters his subject against Tomas Machac and qualifies for the round of 16

What if the best sign of a conquering Novak Djokovic was his irritability and his displays of temper on the court? This Friday, in the third round of the Australian Open against Tomas Machac, the ten-time winner of the tournament dominated his game and alternated between annoyance at the Czech's balls which took the line, anger against some spectators and jokes, as when he pretended to blow on the ball to force a lob that was too long from the Czech out of the court in the first set. All before winning in three sets (6-1, 6-4, 6-4) in less than 2h30 and answering, at the same time, a few questions.
