Jason Roy says England’s stinging defeat by Australia in the World Cup group phase gave the hosts a “good kick” and helped them rediscover their mojo.

England will step out at the “home of cricket” on Sunday as favourites to lift the trophy for the first time against a New Zealand side also looking to make history.

Last time they were at the ground they were pushed to the brink of a group-stage elimination by a 64-run loss to 2015 World Cup winners Australia.

Jolted by that result, England tapped into a do-or-die mentality -- confidently beating both the Black Caps and India to seal their knockout place, then exacting revenge against their Ashes rivals with a resounding semi-final win at Edgbaston.

“We didn't get too down or upset,” said Roy, whose brilliant form with the bat has underpinned England’s improvement.

“It gave us a good kick and pushed us to actually bring out the best in ourselves I think, and that stands us in good stead for the final,” he added.
