Roma could move 12 points clear of arch-rivals Lazio in Serie A with victory in the Derby della Capitale on Sunday.
Rudi Garcia's men currently sit a point adrift of league leaders Juventus, having closed the gap with a 1-0 midweek victory at Udinese.
The Rome derby - one of the fiercest rivalries in European football - highlights this weekend's action and gives Roma a chance to climb above the defending champions - if only briefly ahead of Juve's meeting with Napoli later on Sunday.
Garcia's side will also revel in the chance to put real daylight between themselves and their neighbours and defender Davide Astori knows his side are entering a crucial period of the campaign.
"Now the fun begins, because we have closed the gap on the top of the table," he is quoted as telling Radio Roma.
"Every point now becomes important, not decisive, but really something to think about. On Sunday we have the first opportunity to go above Juventus.
"We have the ability to be a great team, we need results such as the ones which could occur on Sunday to boost our confidence."
