Dhawan played an important part in India's consecutive wins over Pakistan and South Africa, hitting 73 and 137, and Shastri took potshots at those who had questioned the opening batsman's place in the squad.
"It was a clinical and professional performance, in batting, bowling and fielding, covering all the departments of the game. It was fabulous. When they play like that you think they can achieve anything. Today, I never thought that the players were detached for a single moment or dropped their guard. They were focussed all through," Shastri said after India's 130-run thrashing of South Africa at the MCG.
Praising the players for their "fabulous" fielding and bowling, Shastri said he thought it was like Australia or South Africa playing, instead of India.
"Fielding was fabulous, bowling also. You would think it was Australia or South Africa not Indian players fielding. But when Australia or South Africa does that, people sit up and say fabulous fielding, not in case of India. The same in bowling. When our three pacers were bowling 140km/h, people will not say what a fabulous bowling," he said.
