The greatest club football competition in the world is back, and so are Chelsea after missing out on the Champions League for the 2018/19 season.
Frank Lampard's side were drawn from pot one after their victory in the Europa League last season under Maurizio Sarri.
After being one of the first eight teams to be pulled out in the draw, they were placed into Group H in a ceremony staged in Monaco.
Barcelona, Real Madrid, Juventus and Bayern Munich were among the other top European clubs finding out their opponents.
This year, the other Premier League representatives are Liverpool, Manchester City and Tottenham Hotspur, with the English quartet looking to follow in the footsteps of the Jurgen Klopp's team and their title-winning campaign last term.
The full group stage draw can be found below for Chelsea in Group H as it is drawn.
