Antonio Conte's side face opponents from Spain, Italy and Azerbaijan as they return to Europe's premier club competition
Chelsea have been drawn against Atletico Madrid, Roma and Qarabag in Group C of the 2017-18 Champions League.
The encounter between Antonio Conte's side and Atleti is sure to be a particularly feisty affair - especially considering the indefinite exile of wantaway striker Diego Costa, who is keen to return to Madrid.
Antonio Rudiger will be back at his former club as the Blues take on Serie A outfit Roma and there will be a long trip to Azerbaijan to face Qarabag.
