England v Argentina: Stuart Lancaster delighted by first-half but says game management a priority The game will be won or lost next week on who manages their game the best and that's certainly something we're going to need to take a look at with our second-half performance. Despite struggling in the final 40 minutes, Lancaster said the positives of the first half outweighed the negatives and his players were full of confidence going into next week's eagerly awaited showdown with the world champions. Asked whether England would take heart from their epic 38-21 victory over the All Blacks at Twickenham a year ago, Lancaster said: "I think you have to give New Zealand the respect they deserve as a team and certainly, from our point of view, we'll be doing that. But you've also got to give your own team self-belief and belief that they can win, and I think how we approach the review of this game, the lessons we learn, and how quickly we come up with the answers in terms of where we think we can challenge New Zealand will be key to Monday and Tuesday. By Thursday and Friday, it's the players who will have ownership of it and they have to drive that. They're delighted they've got two from two. That's nine out of 10 internationals we've won now, so we don't need any confidence-building. But we recognise the challenge that's coming our way. Andy Farrell, the England defence coach, was impressed by the way his players took the game to Argentina's powerful forwards but said the players lacked "patience" in the second half. "First half we settled down brilliantly," he said. Argentina were hanging on by the skin of their teeth and the game was set up brilliantly for us at half-time but just couldn't keep it going. There aren't many teams who maul Argentina like we did. In the second half we lacked a bit of patience and conceded a few penalties.
