Roma's miserable year continued as they lost 2-0 at home to Fiorentina and were eliminated from the Coppa Italia quarterfinals on Tuesday.
Mario Gomez scored twice to send Fiorentina, who lost last year's final to Napoli, through to a semifinal against Juventus.
After beginning 2015 with a narrow win over Udinese, four successive draws have seen Roma fall seven points behind Serie A leaders Juve and the capital side's title hopes slip away.
Gomez, who ended an eight-month scoring drought at the end of November, broke the deadlock in the 65th minute, dinking Manuel Pasqual's cross over Roma goalkeeper Lukasz Skorupski from close range.
The two combined again in the final minute, with Gomez controlling another Pasqual cross before firing under the bar.
Roma were booed off the pitch.
