The reigning holders will welcome the Championship side to Stamford Bridge while non-league sides could await Arsenal and Tottenham
Holders Chelsea will begin their FA Cup defence with a home tie against Nottingham Forest, while Arsenal could face non-league opposition in the third round.
The Blues beat Manchester United 1-0 at Wembley in May thanks to an Eden Hazard penalty, in what proved to be Antonio Conte's last game as head coach.
Championship Forest were 4-2 winners over Arsenal in the third round last season and Unai Emery's men could have a venture into the unknown if Solihull Moors of the National League can overcome League One Blackpool in a second-round replay.
