Chelsea open their 2017-18 UEFA Champions League campaign with a visit from Azerbaijan champions Qarabag FK at Stamford Bridge on Tuesday.
The Blues are back in the competition, having missed out last season, but face a team who are in the Champions League group stages for the first time in their history.
As such, little will be expected of Qarabag in their debut in Europe's top competition, particularly with Atletico Madrid and Roma making up the rest of Group C.
Here's everything you need to know about Tuesday's clash.
Time: 7:45 p.
