Simon Shaw believes England must pay more respect to their opponents if they are to avoid a repeat of the RBS 6 Nations heartache suffered against Ireland.
The 37-year-old Wasps lock saw his Grand Slam aspirations fall at the final hurdle for a third time, after twice losing to Ireland and also to Scotland, and hopes England can overcome their own shortcomings ahead of the World Cup in September.
Shaw believes an impressive victory over Wales was followed by Martin Johnson's side doing just enough to beat Scotland and France which led to failure against Ireland, and he told the Daily Telegraph: "In order to have beaten Ireland, we really needed to have raised our game to another level from the intensity we produced in Cardiff."
He added: "I still believe, though, that if we get that right in New Zealand, there is no reason why we can't go on to reach the final, as we did in 2007, and go one better this time."
He believes England were well prepared to beat Ireland but did not want to win as much as their opponents.
"Passion plays a key part and there was clearly a great motivation for Ireland to spoil our party - and they came out and played unbelievably well," he said.
"You can do all the training, all the planning and video analysis but ultimately nothing that you have seen in the past prepares you for what is to come."
