Head coach of Germany
On 13 July 2006, following Klinsmann's decision to not renew his contract, Löw was named as the new head coach of Germany. Löw obtained a contract for two years and announced that he wanted to continue in the philosophy developed by Klinsmann and himself. He declared that his aim was to triumph at Euro 2008. His first game in charge, a friendly against Sweden in Gelsenkirchen on 16 August 2006, was a 3–0 success in which Miroslav Klose scored twice and Bernd Schneider scored the other. With wins over Republic of Ireland and San Marino Löw also had a successful start in qualifying for Euro 2008. On Saturday 7 October 2006 the German "Elf" won 2–0 against Georgia in the Ostseestadion in Rostock, which was the fourth consecutive success for Joachim Löw and his team, in fact the best start of a new head coach of the German national team ever. The team extended this record to five wins in the next challenge, the Euro 2008 qualifier against Slovakia in Bratislava on Wednesday 11 October, with an effective 4–1 victory. The Slovaks' strike was also the first goal conceded by Germany under Löw's reign after a total of 418 minutes played with clean sheets. From www.joozone.com.
The next match saw the end of Löw's perfect record, with the 15 November qualifier in Nicosia against Cyprus (Euro 2008 qualification match) ending in a disappointing 1–1 draw. On 7 February 2007, in a friendly in Düsseldorf, Germany beat Switzerland 3–1. On the 24 March 2007 a 2–1 away-win against the Czech Republic (the strongest competitors for the Euro 2008 Qualifying Group D lead). The winning streak ended on 28 March 2007, right after the triumph against the Czechs when Löw used an experimental squad against Denmark where the team lost 0–1. After that match they won against San Marino 6–0 and Slovakia 2–1 for the Euro 2008 qualifiers and also against England 2–1 at the new Wembley Stadium and Wales 2–0. This result meant that following the match Löw's record stood at 11 wins, 1 loss, and 1 draw from 13 matches and a 41:6 goal difference.
In Euro 2008, as one of the favorites for the competition, Germany defeated Poland 2–0 in their first game, with two goals from Lukas Podolski. In their second game, Germany were beaten 2–1 by Croatia. In their final group game against Austria, Löw was sent to the stands by the referee Manuel Enrique Mejuto Gonzalez along with his Austrian counterpart Josef Hickersberger for arguing with the fourth official. Following his dismissal, he was seen talking to Angela Merkel, Germany's Chancellor, about the incident. Germany won the match 1–0 and progressed to the Quarter Finals of the tournament. Here, though he was forced to watch from the sidelines, his team defeated Portugal 3–2.[1] In a highly exciting match against Turkey in the semi-finals, Germany won 3–2. Germany then lost 1–0 to Spain in the European Championship final on 29 June 2008.
In the 2010 World Cup, Germany proceeded through the group stage and met England in the first round of the knockout stage, beating them 4–1 before defeating Argentina 4-0 in the quarterfinals to reach the final four. Germany then lost to Spain 1-0 and failed to make the Final again.[2] They won third place play-off against Uruguay 3-2 on 10 July 2010.
国家队
2004年8月1日，德国足协出人意料地宣布勒夫将担任德国国家队的助理教练，辅助球队的新主帅尤尔根·克林斯曼。克林斯曼曾与勒夫在同一所教练学校学习，深知勒夫的战术指挥才能，因此上任前特别要求足协任命勒夫为球队的助理教练。克林斯曼上任后，一反德国传统的保守战术，为球队灌输了进攻哲学，而勒夫则依此为克林斯曼制定战术。在克林斯曼和勒夫的带领下，德国在2005年联合会杯中一路打入四强，仅在半决赛以2-3惜败于巴西，但随后他们又在第三名争夺战中以4-3击败墨西哥，最终获得联合会杯季军。本文来自作文地带。
2006年德国世界杯的揭幕战，由克林斯曼和勒夫带领的德国以4-2战胜哥斯达黎加，随后小组赛又相继战胜波兰和厄瓜多尔，以3战全胜的成绩进入淘汰赛。16强的比赛中，德国以2-0轻取瑞典，随后点球力克阿根廷，与意大利会师半决赛。对垒意大利时，双方直到119分钟均未取得入球，但在最后补时阶段意大利连入2球，以2-0取胜。失利后，勒夫帮助克林斯曼重整球队，在第三名争夺战中以3-1击败葡萄牙，获得世界杯季军，勒夫及克林斯曼也因此在德国国内声威大振。
世界杯后，克林斯曼出人意料地决定不与德国足协续约。勒夫随即于2006年7月12日被任命为新的德国国家队主教练，并与德国足协签下了2年合约。勒夫在签约后表示，他将继续奉行克林斯曼制定的执教方针，并且定下在2008年欧洲杯夺冠的目标。2006年8月16日，勒夫带领下的德国迎来首场比赛，在盖尔森基兴迎战瑞典，结果德国以3-0取胜。随后3个月内，勒夫的球队在欧洲杯预选赛中取得3连胜，对手分别是爱尔兰、圣马力诺和斯洛文尼亚。在战胜斯洛文尼亚后，勒夫已率领的德国取得5连胜，创下了德国新任教练战绩最好的纪录。
2007年8月22日，德国在新温布利球场举行的一场友谊赛中以2-1击败英格兰[4]，将勒夫执教的战绩延伸至11胜，1和，1负，进41球失6球。10月17日，德国在已经提前锁定欧洲杯名额的情况下在安联球场迎战捷克。由于有所保存实力，德国以0-3意外落败。这场失败意味着，德国将排在捷克之后以预选D组第二名的身份参加欧洲杯决赛圈[5]。
2008年欧洲杯，勒夫带领阵容不整的德国出战。小组赛以2胜1负的成绩出线后，勒夫面对夺冠大热门葡萄牙。在不被看好的情况下，德国队以3-2击败葡萄牙，晋级4强。而勒夫由于遭到禁赛而被迫在包厢里观看此场比赛。在半决赛以3-2逆转土耳其后，德国与西班牙在决赛相遇。尽管勒夫尽其全力，但实力不及对手的德国最终以0-1负于对手，遗憾地获得亚军。
2010年世界杯，勒夫带领平均年龄只有25岁，32队中平均年龄最小的德国国家队出战赛事。当中德国的表现出色，在分组赛以4-0击败澳大利亚；以1-0击败加纳，惜以0-1不敌塞尔维亚，终以首名晋级。 在1/8决赛赛事，德国以4-1大胜英格兰晋级，但赛事中英格兰有一球入球备受争议。在1/4决赛赛事中，德国又再大胜阿根廷4-0晋级四强。可惜在四强中未能击败西班牙，重蹈2008年欧锦赛覆辙，以0-1落败。最后，德国在季军战3-2胜乌拉圭，成为2010年世界杯季军。 虽然德国未能在2010世界杯得到冠军，但年轻的德国队在此届的表现令人刮目相看。主帅勒夫的战术亦受到赏识，不少人都希望世杯后他能继续留任，带领德国队在2012的欧锦赛和2014的世界杯夺冠。
