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.
Chelsea 16/1 for Champions League glory
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.
Atleti won their group with 15 points last season and advanced to the semi-finals, while Qarabag and Roma were knocked out in the qualifying rounds. Chelsea, of course, did not participate.
Matches will kick off on September 12, with the group concluding on December 5.
