Full steam ahead for Roger Federer in Australian Open

Roger Federer insists his bid to win an 18th grand slam title in Sunday’s Australian Open final will not be hampered by injury.

Federer held off a thrilling fightback from Stan Wawrinka to win their semi-final 7-5 6-3 1-6 4-6 6-3 on Rod Laver Arena but had to call a medical time-out at the end of the fourth set.
