Luciano Spalletti believes his side has improved considerably since their last meeting with Atalanta, and hopes they have learned the lessons from that game ahead of Saturday's clash.
The game at the Stadio Olimpico is a chance for the Giallorossi to gain a measure of revenge on Gian Piero Gasperini's side - after losing 2-1 in Bergamo when the played in the first half of the campaign.
"Since the game earlier in the campaign we've worked hard and focused on our own season. In my opinion, we've become a better side," Spalletti said.
"There are still some things that aren't perfect. In the first game we got the second half wrong, especially the very end of the match. We failed to take our chances and Atalanta were very good.
"There are plenty of potential pitfalls in tomorrow's match - Atalanta have maintained great form in the league. Roma will need to produce a top performance, but I'm convinced that we'll step up."
The visitors will be without captain Alejandro Gomez, although Spalletti might not have every player available to him either.
"It's a big loss because he's a great player, a fantastic player," Spalletti said about Gomez. "He's good enough for a top team. It's a boost for us if Papu [Gomez] is out.
On his own squad, he added: "Emerson Palmieri won't be in the squad. [Daniele] De Rossi is recovering, but we'll have to see how he gets on in training and how much he's improved today.
"I hope to have him available because he's an important player, so we'll do everything we can to get him back."
