At 36 years of age, you'd be forgiven for thinking Roger Federer would be winding down his Tennis career with less dominating performances than we were used to seeing at the Swiss star's prime.But the 19-time Grand Slam champion is storming through the 2018 Australian Open, not dropping a set in his five matches, and is primed for a semi-final showdown with the South Korean wonderkid Chung Hyeon.The 21-year-old got through the Serb Novak Djokovic in the last 16, in Nole's first Grand Slam since Wimbledon in the summer of 2017, and overcame the challenge of American Tennys Sandgren in their quarter-final clash in straight sets.Federer meanwhile recorded a 7-6, 6-4, 6-3 victory against Czech Tomas Berdych in the last eight, but what interviewer Jim Courier really wanted to probe Federer about was his fascinating attire, and more specifically, his trainers.With the majority of the Nike-sponsored athletes sporting pink ensembles this tournament, Federer decided to wear a fascinating pair of footwear, emblazoned with Melbourne's Flinders Street Station with the number five next to it, titling Federer's amount of wins of the Norman Brooks Cup, which is awarded to the winner of the Men's tournament.'Fed' however stated that the trophy is not allowed on his trainers for undisclosed reasons."So I think storytelling is really important in sports, where we come from and what we do, the places we play in, and actually why do we have the station on there? It's because we aren't allowed to put the trophy on there!" Federer said, as per Eurosport."The trophy was on there once upon a time but it's all good. The tournament has got to do what it's got to do. It's all good. But I like the station better. For Wimbledon we put other stuff on it, the London Eye we had on it.

"Honestly it's great. I think the people enjoy it too, it's maybe better than the trophy but Norman is a good friend by now.

Courier continued to enquire about Federer's attire, with the Swiss great joking that he was thrilled that former world number one Courier liked his outfit.

"I'm very happy that you like it too, it's important for my sleep tonight when I close my eyes!" he joked. "I'll think 'Jim approved my look so it's all good'."
