Coming to bat at the no. 4 position, Pandya played a delightful 78-run knock off 72 balls to steer India home while chasing a competitive 294 for a win.
Kohli also heaped special praise on Pandya and termed the "explosive" all-rounder as a "great asset" for the team.
"I'm really, really satisfied with the win. He (Pandya) is a star, has the ability with the ball, bat and the field. We need a guy like that, we've been missing an explosive all- rounder. He is a great asset for Indian cricket," Kohli said after the match.
