Bernard Tomic has insisted that he is not feeling under any extra pressure to enjoy success after reaching the fourth round of the Australian Open.
The 22-year-old set up a meeting with seventh seed Tomas Berdych by beating fellow Australian Sam Groth in straight sets on Friday, and he is confident of maintaining his best form as he looks to reach a Grand Slam quarter-final for just the second time.
"I don't have any pressure anymore. For me, you know, I do what I need to do. I sat down the last few weeks and said, I want to remain inside the top 50, 60 until after the Australian Open. Now I am looking after this tournament somewhere in the 40s," Tomic told reporters.
"I'm going to try and win. I'm very confident. A huge plus for the next six months, so yeah."
Tomic has recorded just two wins over top-10 players at Grand Slams, with both victories coming at Wimbledon in 2011.
