Dominic Thiem is into the Australian Open quarter-finals after producing an almost flawless performance to beat Gael Monfils 6-2, 6-4, 6-4 on Rod Laver Arena. The fifth seed put in a high quality display to eliminate Monfils from the competition in one hour and 50 minutes. The Austrian will face either Rafael Nadal or Nick Kyrgios in the quarter-finals. Kyrgios and Nadal would have every right to feel concerned about coming up against a red-hot Thiem, who took the first set without facing a single break point. Thiem had a similarly comfortable second set, despite some party tricks from Monfils, as the Frenchman struggled to make any inroads on his first serve. And with the momentum swung well in Thiem's favour, the 26-year-old raced through the third set to secure a place in the quarter-finals for the first time in his career. "I played my best match so far at this Australian Open. I had a good feeling and also the score looks way easier than the match was. "I think I was lucky to make an early break in each set and managed to hold my serve well. I'm so happy because I'm in the quarter-finals for the first time here. "It's really lucky that I'm still unbeaten against him. "The last matches were always in a late stage and I always played my best tennis against him so that's maybe one reason."
