Although both players are seen in the background as the camera focuses on Indian coach Ravi Shastri in the short clip, it has been enough to capture the attention of fans on Twitter since Friday.
“What has siraj done here for kuldeep,” the Twitter handle of a fan page of Indian captain Virat Kohli said, tweeting the clip from the live show.
Another tweet by the same handle then asked people not to take the video too seriously and that the two were “best friends.”
Siraj and Kuldeep were not selected for the first test.
Siraj, India’s top wicket scorer in their 2-1 victory in Australia, was benched as veteran Ishant Sharma returned to the squad. Spinner Shahbaz Nadeem was selected ahead of Kuldeep in the absence of versatile Ravindra Jadeja.
