Roma was held to 1-1 at Palermo on Saturday in another slip-up in its quest for the Serie A title.
Rudi Garcia's team fell three points behind Juventus after last week's derby draw against Lazio, and the defending champion can pull further ahead when it hosts Hellas Verona on Sunday.
Paulo Dybala returned from injury to stun Roma by firing Palermo ahead in the second minute following a defensive error. Mattia Destro levelled nine minutes into the second half.
Palermo remained level on points with Inter Milan, which was fortunate to leave relegation-threatened Empoli with a 0-0 draw.
Both are level with AC Milan in mid-table, but just five points below third-placed Lazio ahead of the rest of the weekend's fixtures.
