Injury ‘No Worry’

Federer unusually took a medical timeout in his three-hour, five-minute battle with Wawrinka, saying he had been carrying an upper leg injury.

He said he was not worried about it and nothing was going to stop him from taking to the court and fighting it out for a fifth Australian Open crown on Rod Laver Arena on Sunday.

“I’ll leave it all out here in Australia and if I can’t walk for another five months, that’s okay. I’ll give it my best shot,” he said.

“It feels amazing. I never, ever in my wildest dreams thought I would come this far in Australia. I have a couple of days off. It’s beautiful, I’m so happy.”

The 35-year-old superstar, who had returned to top-level tennis after a six-month injury lay-off, booked a spot in his 28th Grand Slam final with an inspiring victory over the 2014 title holder and fourth seed.
