Unai Emery has insisted that he will be taking this competition seriously, but could be tempted to name a second-string side with Sunday's 12pm Premier League clash on his mind.
Qarabag featured in last season's Champions League group stage and were hit for six at Stamford Bridge against Chelsea, but held their own against Atletico Madrid, drawing twice.
Eden Hazard beginning to fizz. Paulo Vinicius covers well to stop Alvaro Morata having an effort on goal.
Another corner, and subsequently another one. 15 on the night with more than 20 minutes still to go, and Chelsea haven't had a real effort on goal directly from any of them.
First touch for Barkley, getting the ball out of his feet and bending one round a defender as he looks to find the top corner. The curl on the ball takes it comfortably into Tomas Tujvel's gloves, however.
Another change for Chelsea: Ruben Loftus-Cheek has had an encouraging night on his return to the team. Fittingly, on comes Ross Barkley, today named in Gareth Southgate's England squad somewhat replacing Loftus-Cheek.
On the counter Milanov gets free, crosses for Boban Nikolov who tries to return the favour, but Andreas Christensen cuts it out and Vidi will have a corner.
It comes to nothing, but Vidi are creating chances.
Georgi Milanov jinks his way past a Chelsea defender and has a great sighting of goal on his left foot, but the ball is bouncing slightly and he puts this one into the 15th row in the stands.
Another opening for the visitors and a warning sign for Chelsea. It is still 0-0 at Stamford Bridge.
Roland Juhasz shows his power to prevent Alvaro Morata latching on to another clipped ball in. Tomas Tujvel welcomes the ball into his arms and Vidi can pump the ball long.
The visitors defended resolutely in the first half and captain Roland Juhasz lead from the front. They've slipped back into their shape naturally at the start of the second half.
Emerson presses forward and earns Chelsea their tenth corner of the game. Can they make one count in the second half?
Again Chelsea can't force a chance from the ball in, and the half-time whistle is blown. 16 shots, 9 corners and a big penalty appeal but no goals as of yet for the home side. 0-0.
Brilliant from Loic Nego. The Frenchman outmuscles Emerson, cuts back on to his left foot past Andreas Christensen but rather hacks at the ball and it is very easy for Kepa to claim.
