England head coach Stuart Lancaster has admitted that his side will need to be at their best if they are to compete with New Zealand on Saturday.

England face the All Blacks after back-to-back defeats against Australia and South Africa, and while Lancaster acknowledges that his team improved last weekend, he has admitted that it will be a "huge challenge" to beat New Zealand.

Lancaster told reporters: "I am looking forward to a huge challenge this weekend.

"I thought we stepped up our performance in a few areas last weekend but we will need to be at our best in all areas for what will be a formidable challenge against the All Blacks."

South Africa edged out England 16-15 at Twickenham last weekend.
