Arsenal added more league and cup doubles in 1998 and 2002, and in 2004 became the first club in Premier League history to win the title without a single defeat. The side, nicknamed "The Invincibles" remained unbeaten for 49 games, before losing to Manchester United in October 2004. In 2006, Arsenal reached their first UEFA Champions League final but Barcelona scored twice in the second half to win the competition. Later that year, Arsenal moved to the Emirates Stadium which commenced a transitional period. Though the club strengthened their position in the league's "top four" and frequently participated in the Champions League, they struggled to hold on to their best players. In 2011–12, Arsenal made their worst start to a season for 58 years, but a strong finish saw the club overtake rivals Tottenham Hotspur to third position. After nine years without silverware, the club beat Hull City to win the 2014 FA Cup Final and retained the trophy with a dominant display against Aston Villa in 2015, before clinching a record 13th in 2017. Arsenal won their fourteenth FA Cup in 2020, beating Chelsea.
