Vunipola urges England to improve

England prop Mako Vunipola has called for improvement from his team-mates against Australia when the sides meet at Twickenham on Saturday.

England defeated Argentina 21-8 at the weekend but their performance left a lot to be desired.

Nathan Hughes and Semesa Rokoduguni both scored tries for an England side that also made countless errors on their way to a hard-fought victory. This has made Vunipola warn his side that they must imrpove their performance before facing the Wallabies.

"It shouldn't happen again," the Saracens loosehead prop told Sky Sports after being named man of the match on Saturday.

"The team Australia are at the moment and the form they are in, they will take you apart if you don't have that cohesiveness.

"We are obviously pleased to get a win against a good side but we know we could have played a lot better. There was a lack of patience but also accuracy. We have to learn from it."
