The second Derby della Capitale of the season takes place at Stadio Olimpico on Wednesday (KO, 17:00), as city rivals Lazio and Roma face off in the quarter-finals of the Coppa Italia.
The sides couldn't be separated in the Eternal City last month as they played out a 0-0 draw in Serie A, where there is just a point separating them at the halfway stage.
Lazio should come into this one as the more confident of the two having won their last three games, while Roma's start to 2023 has been uncertain as they followed up a nervy 2-1 win over Cremonese in the last round of the Coppa Italia with a 1-1 draw against Atalanta on Sunday night.
Lazio captain Ciro Immobile has missed his side's last two matches with a hamstring injury and the striker looks set to be sidelined again on Wednesday. Another long-serving player, Luis Alberto, has been out for the same duration, and will miss out once more.
Manuel Lazzari, Elseid Hysaj, Matias Vecino, Felipe Anderson and Pedro are among those head coach Maurizio Sarri could turn to if the Italian tactician decides to make changes from the line-up that beat Udinese 2-1 on Sunday. Vecino in particular will be hopeful of a starting spot after scoring the winner off the bench in Udine.
The visitors are missing several players themselves with the absences of Houssem Aouar and Evan Ndicka - who are both at the Africa Cup of Nations - compounding the serious injuries sustained to Tammy Abraham, Marash Kumbulla and Chris Smalling.
Renato Sanches, meanwhile, has not been named in a squad since coming on at half-time against Bologna on December 17 and being hauled off 18 minutes later.
Goalkeeper Mile Svilar started the last round of the cup so the 24-year-old Serbian will hope to get the nod ahead of Rui Patricio in midweek, while Leonardo Spinazzola, Leandro Paredes, Zeki Celik and Stephan El Shaarawy are all in with a chance of starting back-to-back games in the competition.
Paulo Dybala could drop to the bench given his injury history, but Romelu Lukaku is expected to start in attack again, possibly alongside Andrea Belotti.
Lazio are 7/4 to win Wednesday's clash inside 90 minutes, with a victory for the visitors priced at 6/4. The draw, which would send the tie to extra-time, is available at 15/8.
Both teams to score is EVS and it's 6/4 for over 2.5 goals.
Under 1.5 goals @ 6/4
Goals have been scarce in recent meetings between these two sides, with last month's 0-0 draw following a pair of 1-0 wins for Lazio in the previous season.
Lazio have already been involved in seven games with one goal or fewer this term, with the number at four for Roma.
Given the stakes on Wednesday, and the potential absences of some of the sides' most potent players - chiefly Immobile and Dybala - a low-scoring match appears a concrete possibility.
Half-time correct score - 0-0 @ 6/5
Goals appear even more unlikely in the first-half - neither of the Rome derbies in 2023 featured one before half-time, and two of Roma's last four matches have seen Jose Mourinho's side go into the interval at 0-0.
Lazio's last game at Stadio Olimpico - a 3-1 win over Frosinone on December 29 - saw all four goals scored in the second period, the fifth time this season that no goals have been scored in the first-half of a Lazio game.
It could well be another tight affair between the bitter rivals in the opening half of their Coppa Italia quarter-final.
