From an England point of view they have put money into white-ball cricket because our performances in World Cups has not been good enough, I understand the reasons for that.

I've always felt that when I've been successful in red-ball cricket it has been because I've left the ball well and sometimes in cricket the shots you don't play are more important than the ones you do.
