England captain Steve Borthwick has challenged his side to discover their maximum potential against New Zealand this weekend.
Martin Johnson's team have come under fire for their displays in defeat to Australia and an uninspiring win over Argentina.
The All Blacks are next up on the autumn schedule and Borthwick insisted: "We are making sure we are putting the hard work in, and making sure we are better than last weekend.
"We have not played to our potential and the challenge is to play to our limits and find out exactly where our limits are - maximise our ability. We have not played to our potential."
Borthwick added on Sky Sports News: "We know New Zealand are a top-quality side and that makes this weekend such an exciting challenge.
"We need to do what we are doing better. With each week we spend together we find out more about ourselves, we find out where our strengths are and where our weaknesses are."
