the second tier of the Swiss league system. Since then, Vaduz have been one of the best teams in the Challenge League and gave serious challenges towards promotion to the Super League, especially in 2004 and 2005, playing two-leg play-offs in both cases. In the 2007–08 season, Vaduz secured promotion to the Swiss Super League on 12 May 2008 by winning the Challenge League on the final day of the season, giving Liechtenstein a representative at the highest level of Swiss football for the first time. Vaduz, however, were relegated back to the Challenge League after one season in the top flight. Vaduz finally returned to top level after five years in the Challenge League. In May 2010, the two Liechtenstein teams FC Vaduz and USV Eschen/Mauren decided on a better cooperation, especially on the exchange and the development possibilities of the players of both teams. In principle, the agreement should replace the missing substructure at FC Vaduz and promote cooperation in the sense of Liechtenstein football. FC Vaduz is the first address for professional footballers. In 1992, Vaduz qualified for European football for the first time, entering the UEFA Cup Winners' Cup as Liechtenstein Cup winners, but lost 12–1 on aggregate to Chornomorets Odesa of Ukraine in the qualifying round.

After the Cup Winners' Cup was abolished, Vaduz have annually entered the UEFA Cup (now the UEFA Europa League) as a result of winning the Liechtenstein Cup every year since 1998, except 2012. However, Vaduz did come within one second of reaching the first round proper of the UEFA Cup in 2002. With the aggregate scores level, and with opponents Livingston scheduled to go through on away goals, Vaduz won a late corner. The ball was sent into the box, and Marius Zarn hit a goal-bound shot. However, the referee blew the whistle for full-time just before the ball crossed over the line, and Livingston progressed through in controversial circumstances. For the 2005–06 season, Mats Gren was a coach. In the first round of the 2005–06 UEFA Cup qualifying, FC Vaduz defeated Moldovan opponent FC Dacia Chişinău. In the second round they met the Istanbul club
