That late Estêvão winner feels like it happened years ago. With Chelsea's joy interrupted by the October international break, Enzo Maresca will be hoping that this does not break the momentum his team gained from that encounter.
He'll have to hope from the stands of the City Ground, as he serves his suspension after being sent off for his joyous celebrations following that 95th minute winner.
One the flip side, it has been a miserable start to life in the Midlands for Ange Postecoglou. Winless in his first seven games, this run of form leaves him on the edge of dismissal just 39 days after joining Forest.
This game could prove a crucial one for Ange, but he will need to change his record against Chelsea. The Australian certainly won't have fond memories of the West London outfit from his time at Spurs.
Forest have been tough customers for Chelsea since their return to the Premier League, but interestungly, their best results against the Blues have come away from the City Ground. In fact, Forest are undefeated at Stamford Bridge since their retun, but winless at the City ground against Chelsea.
Chelsea
Enzo Maresca has a lot of injuries to contend with yet again whilst picking his squad.
There is some good news in the sense that Wesley Fofana, Tosin Adarabioyo and Andrey Santos have all recovered from their respective issues and are ready to be part of the matchday squad.
Trevoh Chalobah also returns from a suspension which he picked up against Brighton, putting in a last-ditch tackle but getting it all wrong.
But there is also a long list of issues for the Blues, with the most concerning being the news that Cole Palmer is set to miss six more weeks at the least.
Maresca was uncertain on the fitness of Pedro Neto, Moises Caicedo and Enzo Fernandez as they had not trained the previous day. They will make a decision on the trio prior to the match.
Nottingham Forest
There is only good news to report on for Forest as the trio of Douglas Luiz, Oleksandr Zinchenko and Murillo are all available after recovering from their injuries over the international break.
There are no new injury concerns for Postecoglou, exactly what the Australian will want to hear.
Predicted Lineups

Key Players
Chelsea - Joao Pedro
The Brazilian enjoyed a lightning-fast start to his Chelsea career, but has experienced a bump in form recently. He simply needs to step up whilst Chelsea are without some of their key player, ensuring that the Blues remain around the Champions League positions.
With three goals and two assists in seven Premier League appearances so far, it is important that Pedro breaks this goalless run as soon as possible. He could well do this against Forest, a team that has struggled defensively since Postecoglou's arrival.
Nottingham Forest - Murillo
He could not have picked a better time to return if he tried. Murillo could be the difference maker in the encounter with Chelsea. The Blues frontline will be confident following their victory against Liverpool, therefore Forest will need to counter this.
Murillo has so often been a commanding leader in Forest's backline and will need to be against Chelsea if the Tricky Trees want to end a bad run of form that sees them just one point off the relegation zone.
