Switzerland's Roger Federer reaches for a backhand return to Britain's Daniel Evans during their second round match at the Australian Open tennis championships in Melbourne, Australia, Wednesday, Jan. 16, 2019.
"I think what's key is just going out there and playing really well, just doing the best that you can do", she said.
"It always helps when you sneak in a quick break, win the first set and then maybe start pressing even more so".
The Swiss said: "I think he played very well".
'Yeah. I mean, playing against him is a lot... it's a lot easier to play against him, to play well against someone who's so good, ' he added.
Dan Evans leaves Australia with quite a compliment from Roger Federer - arguably the greatest player of all time - 12 months after he sat at home in Cheltenham despondent while serving a year-long drugs ban and wondering if he would ever play tennis again.
20-time grand slam victor, Roger Federer has made it into the third round of the 2019 ATP Australian Open.
Istomin caused a massive upset in Melbourne two years ago when he knocked out defending champion Novak Djokovic in the second round, but was no match for the Swiss great.
Federer rates Evans highly and backed him for a charge up the rankings if he remains focused.
The Serbian player dominated the second half of 2018, winning at Wimbledon and the United States, hence returning to his No. 1 ranking after a streak of losses.
The 28 year-old Midlander had treatment for a blister on each foot at the end of it, and then played his first poor service game to be broken for the first time. "The energy I feel in this place is fantastic".
Playing attacking shots, Evans had nearly clinched the opening set while serving at 5-4 in the tie break round.
Evans, whose ranking plummeted from a career-high 41 after he was slapped with a year-long ban for testing positive to cocaine in April 2017, played nearly flawless tennis to stave off a set point on his way to forcing a first set tie-break. Federer and Fritz met once before with multiple Grand Slam champ winning in three sets at an ATP tour event to defeat the upstart Fritz.
Asked what he had been doing during last year's Australian Open, Evans replied "I didn't watch any of the matches".
Women's 19th seed Caroline Garcia ended the hopes of Australian Zoe Hives to become the first player into the third round with a 6-3 6-3 victory in just 65 minutes on the 1573 Arena.
Pundits have decried the younger generation's failure to break into the Grand Slam cartel enjoyed by the old guard, but have some tipped change at the top this year. Federer has not lost a single match in Melbourne since 2017, and will look to win his 15th consecutive match here on Wednesday.
