Nottingham Forest resume Premier League proceedings aiming for a first win at the eighth attempt under Ange Postecoglou against a Chelsea side who defeated champions Liverpool last time out.
BBC Sport examines some of the key themes ahead of Saturday's lunchtime clash at the City Ground.
Postecoglou's poor start
Five defeats, two draws and 15 goals conceded is not the start Ange Postecoglou may have envisaged when replacing Nuno Espirito Santo as Nottingham Forest boss.
The Australian has barely been in the job a month but is already facing question marks over his future, with reports last weekend suggesting former Everton manager Sean Dyche is waiting in the wings should Forest's poor form continue.
Postecoglou has now lost 30 of his past 49 Premier League games with former club Tottenham and Forest, a recent record that may not help dissuade his detractors.
However, Forest's problems, particularly in defence, predate Postecoglou's arrival: they haven't kept a clean sheet in any of their past 15 Premier League games, their joint-longest run since returning to the competition in 2022.
And the task for Forest's manager does not get any easier. Next up, its Chelsea and Postecoglou has lost all four Premier League meetings against the Blues.
Chelsea aim to back up Liverpool win
Chelsea counterpart Enzo Maresca had been under some pressure following back to back defeats to Manchester United and Bayern Munich, although a 2-1 victory against Liverpool ahead of the international break has assuaged some of the unease at Stamford Bridge.
Willian Estevao's stoppage-time goal knocked Liverpool off top spot in the Premier League and he is one of several key players whom Maresca will rely on as injuries continue to take their toll on Chelsea's squad.
Maresca could be missing up to nine players for the trip to the City Ground, including Cole Palmer, who has been ruled out for another six weeks due to an ongoing groin injury.
In the absence of other star names, Chelsea's key performer so far this season has undoubtedly been Moises Caicedo.
The combative Ecuador international has been one of the most effective midfielders in the Premier League this season, making more tackles and more interceptions than any player so far.
Moises Caicedo has been in impressive form this season for Chelsea
On Saturday he will face another in-form midfielder in the guise of Forest's Elliot Anderson, who again impressed on international duty with England in the World Cup qualifying win against Latvia on Tuesday night.
The 22-year-old has won back possession a league-high 55 times this season and his battle with Caicedo could go a long way to deciding the outcome of a crucial match for Forest's manager.
