The vast experience of Rafael Nadal meets the exciting youth of Stefanos Tsitsipas in a fascinating first men's semi-final at the Australian Open today.

Tsitsipas, 20, with all the gifts, pulled off the win of his life to knock out Roger Federer in four sets in the Last 16. The 14th seed Tsitsipas has already etched his name in Greece's sporting pantheon by becoming the first player from his country — man or woman — to reach the semi-final of a Slam.
