It's out there in the middle, 11 v 11. It doesn't matter what's gone on before or after. It's those five days.<br /> <br /> "I think every Test series you play for England is a hugely important series, it doesn't matter what has gone before.<br /> <br /> "We are fully focused on these two weeks of Test cricket versus New Zealand. We have to be at our best to win."<br /> <br /> Cook is hopeful the return of off-spinner Graeme Swann and seamer Tim Bresnan from elbow surgery will give his team's bowling attack a cutting edge they lacked in New Zealand.<br /> <br /> "It's great to have Graeme fully fit after his elbow surgery; you want your best players available," he said.<br /> "I think you miss every experienced player who doesn't play. You can't buy experience.<br /> <br /> "It's very crucial you have that. You always miss players of that kind of calibre when they're not around.<br /> "It's obviously great to have Bressie back. His elbow surgery has gone well.<br /> <br /> "With the amount of cricket we have coming up in the next 12 months we're going to need more than 11 players and it's great he's back."
