Serie A leaders Juventus welcome Roma to Turin as the first of three games for Massimiliano Allegri's side in the next seven days before the winter break.
Juventus find themselves 22 points above Roma in the table, and their home draw to Genoa remains the only blemish on their otherwise perfect league record this season.
Eusebio Di Francesco's team meanwhile have lost all of their previous seven visits to the stadium and have won just twice in their last eight league games, the latest of which came against Genoa last weekend.
Hello and welcome to our coverage of the Saturday night fixture in Serie A between Juventus and Roma.
The Turin side are 22 points ahead of the capital side, and have just dropped two points in the league all season.
Roma have never won at the Allianz Stadium in seven attempts, but record are there to be broken right?
Now, where are those teams?
Well, here they are.
If you need a reminder at just what this game means, we only need to look at last year.
Juventus' near 100% record has been well-documented as Massimiliano Allegri's side seem to overcome the obstacles that are placed in front of them.
The league leaders have come through challenges at Fiorentina, Inter Milan and the Turin derby and scored five goals altogether in those games without reply.
Today against Roma and Atalanta on Boxing Day ends what was billed as a tricky month for Juventus, and very few would bet against them remaining undefeated before the winter break.
Roma however have not quite hit the heights expected of them, as they sit some way behind their opponents tonight in the Serie A table.
Eusebio Di Francesco's side lie in 9th, four points off the Champions League places, and have drawn two of their last three league fixtures.
They may enjoy an extended run in this season's Champions League after drawing Porto on Monday, but the priority will surely be making it for next year's competition.
Kick off in just over 20 minutes time.
So, just ten minutes till kick-off. Can Roma put any doubt into the minds of the leaders before the winter break?
Or will Juventus keep up this scintillating home record and make it eight consecutive wins?
So, the players are making their way out for the latest edition of this historic Serie A fixture.
A couple of former Roma players in the Juventus lineup today, with Miralem Pjanic and Wojciech Szczesny having represented the capital side.
All set as the sides walk out to a fantastic display from the crowd.
A true legend.
4 min: Juventus 0-0 Roma
Eusebio Di Francesco is a man under pressure, with rumours that he would have been sacked had Roma lost against Genoa last week.
However, his side have made a nervous start here and only a Kostas Manolas intervention prevents Ronaldo, who was lurking at the back post, from converting Mario Mandzukic's header across goal.
5 min: Juventus 0-0 Roma
That's sloppy from Rodrigo Bentancur, who loses out to Zaniolo, but Nzonzi fires his teammate's lay-off over the bar.
9 min: Juventus 0-0 Roma
What a save from Olsen! Bentancur's long-range effort deflects off Mandzukic into the path of Alex Sandro.
The Brazilian looks set to celebrate his new contract with a goal here, but the Swede gets down well to his left to parry the shot.
14 min: Juventus 0-0 Roma
Roma have settled a little since the early scares and have managed to contain Juventus slightly better.
The hosts still enjoying the majority of possession though.
19 min: Juventus 0-0 Roma
Bit of frustration coming from both sets of players.
First Cengiz Under, who is said to be a target for Arsenal, complains after what he saw as a clear foul on him by Matuidi.
Cristiano Ronaldo similarly is left in shock with the referee's decision not to award a free-kick for a tug on the shirt.
Alex Sandro however continues his good start to the game, forcing a save from Olsen at his near post and then a block from Manolas from the resulting corner.
21 min: Juventus 0-0 Roma
Juventus certainly pose a threat going forward, but so do the visitors. This time it is Patrick Schick who rolls his defender, but his shot is tame and easily collected low by Szczesny.
23 min: Juventus 0-0 Roma
We saw Gareth Bale try one in the Club World Cup final, and now it's time for his former teammate to have a go.
Kostas Manolas makes a mess of clearing Mandzukic's header, and Ronaldo attempts to recreate his overhead kick against Juventus in the Champions League last season, but fires over the bar.
27 min: Juventus 0-0 Roma
Signs of a frustrated crowd already here at the Allianz Stadium, and it is understandable given their start to the season.
The latest attack breaks down after Ronaldo, of all people, takes a heavy touch and allows Davide Santon to clear.
30 min: Juventus 0-0 Roma
Legends on and off the field here at the Allianz Stadium. The Juve fans led a tribute to Claudio Marchisio before kick-off, while Francesco Totti is also in the stands to see his old side in action.
32 min: Juventus 0-0 Roma
Juve have just lost that spark in their play in the last five minutes or so.
Roma have as a consequence grown in confidence and Cengiz Under in particular looks to be a threat.
Alex Sandro has yet another effort meanwhile, but it poses no danger to Olsen's goal.
34 min: Juventus 0-0 Roma
Another fine save from Olsen! The Swede this time extends himself to get to Ronaldo's shot after the Portuguese was given far too much time by the Roma defence.

Cristiano Ronaldo: The Portuguese decided the Turin derby in favour of his side with a well-taken penalty against Torino last weekend. It was his 12th goal in all competitions since joining the club from Real Madrid in the summer, and ensured that Juventus ground out a victory despite a lacklustre performance to extend their lead over second-placed Napoli to 11 points.
