Recent results don't suggest it but the Black Caps maintain they have the ability and self confidence to win the cricket world cup on the Indian sub continent.
The Black Caps play India tomorrow in their final warm up match ahead of the tournament.
Having lost one day series to Bangladesh, India and Pakistan in recent months McCullum says while results haven't gone their way, none of that will count come the start of the world cup.
He says they simply can't afford to think they're incapable of winning.
Their first game of the world cup is against Kenya on Sunday.
