Virat Kohli is a potential captaincy material, but the talented right-handed batsman needs to calm down his enthusiasm to become a good leader in future, feels former Australia skipper Steve Waugh.

"Virat Kohli is a talented player and a potential captain for sure. He is very exciting and has got passion for sure, which is good, but he sometimes needs to pull that enthusiasm inside a bit. He will make a good leader one day," Waugh said on Friday.

Recently, miffed at being given out to a controversial catch during the second One-Day International (ODI) against Zimbabwe, Kohli, who is captaining the side in Zimbabwe tour, ended up arguing aggressively with on-field officials even after the third umpire ruled the decision against him.
