England begin their Autumn Internationals with a match against Fiji at Twickenham on Saturday, and Lancaster believes that they will only earn victory through a 'complete performance'.
Lancaster told reporters: "We need to produce the complete game. People talk about attack, but it is about game management as well.
"It is about playing well in the right areas of the field. We need to play well in attack, defence, at set pieces and game management.
"Those four components are critical to win not just this weekend's game, but every game that we play."
The match with Fiji is the first of four internationals that England will play through the autumn.
