Kuhn was promoted to coach of the senior national team in June 2001, replacing the Argentine Enzo Trossero. Kuhn had been approached to become Trossero's assistant, but turned down the offer. With no real senior coaching experience, his appointment as head coach was first not universally applauded, but he has led the Swiss to Euro 2004 and the second round of the 2006 World Cup. Since Kuhn took part in the 1966 World Cup as a player, Switzerland had qualified for just one World Cup, in 1994, and one Euro finals, in 1996. Kuhn spent seven years as coach of the national team, and utilised many of the youth players he had worked with at youth level, ultimately helped building a successful football generation that would be later inherited by Ottmar Hitzfeld. He is second in all-time matches coached for the Swiss team, behind Karl Rappan.
