Kolkata Knight Riders head coach Brendon McCullum believes the Australian Test captain Pat Cummins would add an element of leadership for captain Shreyas Iyer to feed off.

"Pretty delighted to get Pat back. He's going to add another layer of leadership in and around our skipper Shreyas, who has been impressive as well. We have got a few selection headaches actually. We have more guys to pick from than not, which is a good problem to have and hopefully we get them right," McCullum told Kolkata Knight Riders' official website.
