The west London club already secured top spot last week thanks a comprehensive victory over closest rivals Sevilla and maintained their unbeaten European campaign as a second-string side drew with Krasnodar on Tuesday evening.
Having picked up 14 points from a possible 18, Chelsea will be one of the most feared sides in the competition going into the draw for the knockout stages.
Although four groups still need to be decided on Wednesday night, Chelsea can already get a good idea of who they might come up against in the last 16.
With two other Premier League sides also finishing as group winners, Chelsea can be drawn against any of the runners-up – save for fellow Group E side Sevilla – and there are some very big names in the hat.
Chief among them is Barcelona, who were beaten at home to Juventus to miss out on top spot, while another Italian side, Lazio, came through their match against Club Brugge in the night’s early kick-off.

RB Leipzig emerged from a very difficult group at the expense of Manchester United and will likely be runners-up, with PSG expected to be awarded a win against Istanbul Basaksehir via a forfeit after the Turkish side’s players walked off the pitch over a racist incident involving the fourth official.
In the other half of the groups, who play on Wednesday night, only Porto are guaranteed to go through as runners-up.
In Group B, meanwhile, all four teams – Borussia Monchengladbach, Shakhtar Donetsk, Real Madrid and Inter Milan – can all still finish as group winners or runners-up, with everything still to play for in the final group games.
When is the draw for the last 16?
The draw for the knockout phase of the Champions League will take place next week, on Monday December 14 at 11am GMT, at UEFA’s headquarters in Nyon, Switzerland.
Clubs from the same national association or group cannot be drawn against one another.
When will the last 16 matches take place?
After a packed schedule of group games, the Champions League takes a pause for two months with the first legs of the last 16 not taking place until February 16 and 17, with the second legs following on March 9 and 10.
Group winners, who are seeded, will play away in the first leg and at home in the second leg.
