Well, quite a night in west London and plenty to absorb from a game with six goals and plenty of frustration for Chelsea. Roma were sensational and deserved at least a point from this one.
That brings an end to our live coverage from Stamford Bridge. We'll have all the reaction over the next 24 hours, and we're back tomorrow night as we follow Arsenal and Everton's fortunes in the Europa League.
But until next time, it's goodbye.
Full time: Chelsea 3-3 Roma
You'll go a long way to find a better group stage game in this year's Champions League.
A six-goal thriller at Stamford Bridge saw Chelsea surround a two-goal lead, Roma come back to lead before Eden Hazard's header saw the points shared.
In the end, it is a missed opportunity for Antonio Conte's men, but they can secure a last 16 berth if they beat Roma in the Italian capital in a few weeks.
Gary Cahill throws himself at the ball but to no avail as it flies over. Was that the last chance?
Four added minutes at Stamford Bridge. Chelsea free-kick just outside the box....
Hazard celebrates after scoring his second and Chelsea's leveller.
Roma defending rather frantically as Chelsea press for a late winner. Stephan El Shaarawy being prepped to come for Roma as a final throw of the dice.
Antonio Rudiger almost comes back to haunt his old club but his mistimes his jumps and it flies off-target. Into the final five minutes. Can either wise get a winner?
Roma so close to grabbing what could well have been the winner. Perez crosses brilliantly and Dzeko out-jumps Cahill but heads wide at the near post.
Dzeko nets his second to put Roma ahead for the first time.
Willian replaces Eden Hazard for the final 10 minutes. Alvaro Morata stays on, bizarrely.
GOAL! Chelsea 3-3 Roma (Eden Hazard)
As you were at Stamford Bridge. Make that three goals in the space of 11 minutes as Chelsea draw level. Pedro clips a lovely ball which Hazard has no choice but to head goalwards from 12 yards and he finds the corner delightfully, despite Alisson's best efforts.
Edin Dzeko thunders Roma level.
You'll have to go a long way to find someone who doesn't agree with their current scoreline. Roma have been magnificent through the 90 minutes and they have produced a fine away display, one of the best you'll see this season.
GOAL! Chelsea 2-3 Roma (Edin Dzeko)
Roma have turned it around at the home of the Premier League champion. Kolarov curls in a peach of a delivery and Dzeko is unmarked and he plants a header firmly past Courtois. You can't say it hasn't been coming.
Nasty collision between Fazio and Pedro as Chelsea attacked and both players have been floored by it. A much-needed break in play after what has been an exhilarating opening three quarters to this game.
GOAL! Chelsea 2-2 Roma (Edin Dzeko)
Exactly what the Italian side deserve. They have dominated from the minute they went behind and now they're favourites to grab all three points. Fazio plays a fine ball over the top and Dzeko comes through on cue and fires a brilliant volley through Courtois.
Michy Batshuayi is ordered to warm-up by Antonio Conte, who is now getting a word spoken to him by referee Damir Skomina, who is not happy with the Italian continually breaching his technical area. Roma still dictating the play.
David Luiz off for Chelsea, with Pedro coming. Has been struggling with a leg injury since the half hour mark, so no surprise to see him come off.
Can't say I'm aware of how Pedro is going to help Chelsea keep the ball better. Will give them an extra outlet on the break through.
How are Roma not level? Kolarov crosses through a sea of bodies but no-one can divert the ball goalwards.
Pedro coming on for Chelsea as Conte attempts to react to his side being totally dominated.
Sums up the game.
It is all Roma again and Strootman has the first effort of the half, latching onto Dzeko's header and seeing his shot deflected wide. Chelsea clear the subsequent corner.
Aleksandar Kolarov pulls one back for Roma.
Back under way at Stamford Bridge. This should be a cracking second half.
