Introduction about the FA cup

The competition is a knockout tournament with pairings for each round drawn at random - there are no seeds, and the draw for each round is not made until after the scheduled dates for the previous round. The draw also determines which teams will play at home.
Each tie is played as a single leg. If a match is drawn, there is a replay, usually at the ground of the team who were away for the first game. Drawn replays are now settled with extra time and penalty shootouts, though until the 1990s further replays would be played until one team was victorious. Some ties took as many as six matches to settle; in their 1975 campaign, Fulham played a total of 12 games over six rounds, which remains the most games played by a team to reach a final. Replays were traditionally played three or four days after the original game, but from 1991–92 they were staged at least 10 days later on police advice. This led to penalty shoot-outs being introduced. Replays are no longer held for the semi-finals or final.
There are a total of 14 rounds in the competition—six qualifying rounds, followed by six further rounds, semi-finals, and the final. The competition begins in August with the Extra Preliminary Round, followed by the Preliminary Round and First Qualifying Round, which are contested by the lowest-ranked clubs. Clubs playing in the Conference North and Conference South are given exemption to the Second Qualifying Round, and Conference National teams are given exemption to the Fourth Qualifying Round. The 32 winners from that round join the 48 clubs from League One and League Two in the First Round (often called the First Round Proper). Finally, teams from the Premier League and Football League Championship enter at the Third Round Proper, at which point there are 64 teams remaining in the competition.
