Klinsmann was an important part of the West German team during the 1990 FIFA World Cup. After qualifying for the round of 16, Germany was to play the Netherlands, against whom they had lost two years earlier in Euro 88. After Rudi Völler was sent off in the 22nd minute, Klinsmann was forced to play as a lone striker. He scored the 1–0 opener and his performance received considerable praise. German newspaper Süddeutsche Zeitung wrote that "In the last decade, not a single forward of a DFB team has offered such a brilliant, almost perfect performance." After further victories over Czechoslovakia (1–0) and England (1–1 after extra time, 4–3 on penalties), he became a world champion after beating Argentina 1–0 in the final. Klinsmann is remembered for being fouled by the Argentinian Pedro Monzón, who was subsequently sent off, reducing Argentina to ten men. Many critics called the incident a prime example of Klinsmann's diving, a claim he contradicted. In an interview in 2004, he noted that the foul left a 15 cm gash on his shin.
On 26 July 2004, Klinsmann returned to Germany as the new head coach of the national team, succeeding former teammate and strike partner Rudi Völler. Klinsmann subsequently embarked on an aggressive program to revamp the management of the team. Bringing fellow German striker Oliver Bierhoff on board helped diffuse public relations duties of the previous combined post away from the actual coaching aspect of the position. Furthermore, he created a youth movement to breathe life into an aging squad on the heels of a disastrous showing at Euro 2004. In the run-up to the 2006 World Cup, Klinsmann attracted criticism from German fans and the media following poor results, such as the 4–1 loss to Italy. A particular subject of criticism was that Klinsmann commuted to Germany from the U.S., which was the target of a campaign by the tabloid Bild. Klinsmann previously eliminated some privileges Bild traditionally had with the national team, such as receiving the team lineup the day before a match and 24/7 exclusive access to the team. His largely offensive tactics have irritated some, who complained he ignored defensive football. He announced a squad of young players for the 2006 World Cup, basing his selection policy on performance, not reputation.
