Ruthless Rafael Nadal brutally swatted aside a bright young star in the Australian Open quarter-finals, before setting his sights on the leading new kid on the block, Stefanos Tsitsipas.

The Spanish second seed continued his relentless progress by slaying giantkiller Frances Tiafoe 6-3, 6-4, 6-2 in just 107 minutes of power-packed, precision tennis. And Nadal, 32, warned Tsitsipas, 20, who knocked out Roger Federer in the fourth round, to be ready as the Spaniard would be at his best in Thursday evening's semi-final.
