The Football Association Challenge Cup (FA Cup for short) is a men's knockout football cup named and sponsored by the English Football Association. The FA Cup is the oldest football match in the world. Football clubs at all levels in England hold one-on-one knockout matches. In the FA Cup, it often happens that low-level clubs eliminate high-level clubs.
There is no seed team in the FA Cup, and the match and home and away games are completely decided by lottery. The competition is divided into eight rounds. The first two rounds were given to amateur teams, League One teams and League Two teams, and the Premier League and Championship teams joined the competition in the third round. The competition is divided into eight rounds. Except for semi-finals and finals, if each lap is tied within 90 minutes, a rematch is required. The rematch will be played between the home and away teams. If the rematch is tied within 90 minutes, it will take extra time to decide the outcome. If overtime doesn't decide the outcome, it will be decided by penalty kick.
Semifinals and finals are held in neutral positions. If the two teams draw within 90 minutes, it will take extra time to decide the outcome. If overtime is still tied, the winner will be decided by penalty kick.
According to the above regulations, both Chelsea and Manchester City lost in the fourth round of the FA Cup, so they didn't play in the next round.
