Novak Djokovic did not appear to be tensed a bit about defending his title in Beijing as he posed for a selfie with fellow tennis star Caroline Wozniacki and brother Marko. Novak shared the picture to his followers on social media.

“Taking a selfie with @CaroWozniacki and my bro @DjokoMare at the impressive birds nest stadium,” Novak captioned his Instagram photo.

Novak had the selfie taken at the Beijing National Stadium, also known as the Bird’s Nest. It is where the World Athletics Championships was recently held.

Novak is playing his first official tournament since winning his second US Open title in September. He advanced in the second round after claiming an easy win over Simone Bolelli 6-1 6-1 in the Beijing opener on Tuesday.

After his first-round match, Novak had a day off to spare, which he took advantage to visit the Great Wall of China, reported ATPWorldTour.com. Novak was joined by his brothers Marko and Djordje at the Mutianyu portion of the said Wonder of the World. The trip was reportedly arranged by China Open’s Organising Committee. Novak, a three-time defending champion, is set to do battle with Chinese wild card Ze Zhang in the second round today. It will be the first time that Novak play the Nanjing-native on professional tour.

Meanwhile, Wozniacki, who claimed her 23rd career title in Kuala Lumpur earlier this year, was playing her third tournament since losing in the second round of the 2015 US Open when she was stunned by low-ranked Czech player Petra Cetkovska 6-4 5-7 7-6(1).

The Dane cruised past her opening round matches beating Serbian qualifier Bojana Jovanovski 6-2 6-4 and Chinese wild card Qiang Wang 7-5 6-0. However, Wozniacki failed to avoid the casualty list when she was upset by 10th seed Angelique Kerber 6-2 6-3 in the third round on Wednesday. She is 36-20 this season and currently ranks World No. 11.
