Today's Australian Open quarter-final between Rafael Nadal and Tomas Berdych has a whiff of cricket's "bodyline" controversy about it.
Berdych comes to the quarters by way of a fourth-round match in which his Spanish opponent Nicolas Almagro angered him by belting a tennis ball at his head.
The Czech, in turn, refused to observe the etiquette of shaking his opponent's hand at the net after the final point, drawing a hostile response from the crowd and prominent figures including the Superbrat himself, John McEnroe, who suggested Berdych needed to "toughen up".
Nadal can restore Spanish honour when he gets on to Rod Laver Arena today. He and Berdych have their own "history".
Six years ago in Madrid, Berdych upset Nadal by signalling to the crowd to be quiet after he beat the Spaniard.
