<P> The 1991 semi-final between Arsenal and Tottenham Hotspur was the first to be played at Wembley, the traditional venue for the FA Cup Final . Two years later both semi-finals were held at Wembley after the Steel City derby between Sheffield clubs Wednesday and United was switched from the original venue of Elland Road, Leeds . This was repeated in 1994, although a replay between Manchester United and Oldham Athletic was held at Maine Road, Manchester . </P> <P> From 1995 to 1999 and from 2001 to 2004 other neutral grounds were used, though in 2000 both matches were played at the old Wembley, in its final year of operation . In 2005 both semi-finals were played at the Millennium Stadium, Cardiff . However, in 2006 the FA decided to revert to the neutral ground system, with Villa Park and Old Trafford hosting the games . </P> <P> In 2003, it was announced that all future semi-finals would be played at the new Wembley Stadium, once it had opened; this took effect in 2008 . The decision was mainly for financial reasons, to allow the FA to recoup some of the costs of rebuilding the stadium . However, the move was to the disappointment of traditionalists and drew criticism from some supporters' groups . </P> <P> In the past a replay match was played if the first semi-final ended in a draw . If the replay match also ended in a draw a second replay match would take place . In theory an unlimited number of games could be played to determine the outcome of a tie . For example, in 1980 it took four games to decide the winner between Arsenal and Liverpool . This is the most games needed to settle an FA Cup Semi-final, although there were several occasions where three games were played . Prior to the 1992 semi-finals, the only semi-final played under different rules to this was the rearranged 1989 semi-final between Liverpool and Nottingham Forest, for which it had been declared in advance that the game would be decided by extra-time and penalties if necessary . </P>
