Kolkata Knight Riders captain Dinesh Karthik admitted it was a disappointing performance in their IPL opener on Wednesday.

“I think we had areas to do well in bat and ball. It was a pretty rusty day to be honest... I don’t want to get too analytical about it, but the boys realise they could have done better,” Karthik said after the 49-run loss.

“Pat Cummins and Eoin Morgan just finished their quarantine today. So it is not easy to come in and play in this heat,” he remarked.

Karthik evaded a query about a change in their top-order, saying: “I haven’t had the conversation about that with Baz (coach Brendon McCullum) but will let you know by the next game”.

Mumbai Indians captain Rohit Sharma said he was happy with his performance.

“It was all about how we executed our plans today and it was all about being ruthless,” he said.
