London, Nov 9 (Reporter) Jos Buttler says he is determined to lead England's white-ball sides into the "next era" after fearing he would be stripped of the captaincy this year. Matthew Mott was sacked as white-ball head coach in July after England failed to defend either of the limited-over World Cups, the BBC reported. Test head coach Brendon McCullum will take on the white-ball sides from January, with Buttler, 34, as captain. Buttler, who has joined up with England for the T20 international series in the West Indies after a calf injury, said he "absolutely" felt he could have been sacked as captain by managing director of men's cricket Rob Key. "But Keysy believed I could lead the team forward and captain into the future," he said. "I had some good conversations with him and I said I didn't want to be doing it because I'm the only person to do it, I want to be doing it because I'm the right person to do it."
