Describing Sunil Narine as the man with a "golden arm", former India captain Sourav Ganguly said the Kolkata Knight Riders' "mystery" spinner would be the team's trump card in the sixth season of the Indian Premier League T20.

"For (KKR skipper) Gautam Gambhir, he is the man with the golden arm. He was the person behind KKR's success last season. He is their trump card and will again create an impact this time," Ganguly said on the sidelines of KKR's six wicket win over Delhi Daredevils at the Eden yesterday.
