Ex-Australian pacer Brendon Julian said the Pat Cummins-led side will "clean up" India in the first Test at Perth in four days. He listed "worrying signs for India", including Virat Kohli's performance in the recently concluded Test series against New Zealand. "Kohli isn't at his best. He's not gelling with the captain (Rohit Sharma) probably and...coach (Gautam Gambhir)," said Julian.
