It has become a mind game if Bailey's thoughts were anything to gauge it by: "Vettori's always someone we will pay the utmost respect to and we'll play him really watchfully."
That's got to be worth a few runs for starters. McCullum must be calling for extra liniment and support tape.
It might be mind games but Tim Southee suggested Vettori was enjoying more freedom of movement after the Sri Lanka match: "There's been less discomfort. He's the best I've seen him in a while."
Southee said the team has noted how slow bowling is impacting the tournament.
"When you come to England you have the perception it'll nip around and pace bowlers will be the main wicket-takers, but the surfaces tend to be dry. Playing two games on them means spinners come into play more in the second match."
He said that is significant, given a lack of swing assistance.
"I'm finding the white balls don't swing as much as they used to. I don't whether it's because the surfaces are more abrasive or it's just a bad batch [of balls]. With the training wickets on most blocks you can get the ball to scuff which helps it reverse swing more. You need that with the new fielding rules where just four men can be out of the circle [at any time]. You need ways to put doubt in the minds of batsmen."
Despite the perceived benefits of two new balls Southee offered a concise assessment of the new ODI fielding restrictions.
"Horrible," he laughed. "You're left scratching your head wanting to have more out but it's something you have to adapt to, like mixing it up using your two [available] bouncers an over."
Bailey hinted at the pressure coming on their middle order after a loss to England and a capitulation for 65 in the warm-up match against India.
"I think the challenge when you've had a couple of poor batting performances is that guys start to doubt their place. We want our guys to go out and have absolute clarity, the freedom to bat the way we know they [normally] bat."
