The club's success in the late 1990s and 2000s owes a great deal to the appointment of manager Arsène Wenger in 1996. Wenger brought new tactics, a new training regime and several foreign players who complemented the existing English talent. Arsenal won a second league and cup double in 1998 and a third in 2002. In addition, the club reached the final of the 2000 UEFA Cup (losing on penalties to Galatasaray), were victorious in the 2003 and 2005 FA Cups, and won the Premier League in 2004 without losing a single match, which earned the side the nickame "The Untouchables"; in all, the club went 49 league matches unbeaten, a national record. Arsenal have finished in either first or second place in the league in eight of Wenger's nine seasons at the club, and they are one of only three teams (along with Manchester United and Chelsea) to have won the league title during the past decade. However, they have been unable to replicate their domestic success in the Champions League, having never progressed beyond the quarter-finals (as of 2005).
