Former England captain Michael Vaughan has challenged Harry Brook to live up to his 'genius' tag during the T20 World Cup Super 8s. The Yorkshireman started the tournament with a fifty against Nepal but has failed to reach 20 in his last three innings, despite 10 centuries in 25 non-Ashes matches including a stunning 136* off 65 balls against Sri Lanka.

Vaughan believes Brook possesses exceptional talent but needs to deliver in major tournaments. 'That innings he played in Sri Lanka, he's just got a genius in him,' Vaughan said on the Stick to Cricket podcast. 'These next two weeks, the Super 8s, go and deliver an 80 or 100 in a big, big game.' The criticism comes as England qualified for the Super 8s after a narrow victory over Italy.

Brook's struggles have been compounded by poor form from opener Jos Buttler, who has failed to make a fifty in 14 international innings this winter. Despite the pressure, Buttler insists he won't compromise his aggressive approach to chase form. 'I'm not going to score them by hiding away or sending anyone else out, I've got to put my own shirt on, mark middle and off we go again,' Buttler said, emphasizing his commitment to playing authentic T20 cricket.
