Chris Smalling plunged Inter Milan further into crisis by heading Roma to a 2-1 triumph at the San Siro which kept his team in touch with Serie A leaders Napoli, 3-1 winners over Torino.
England defender Smalling perfectly met Lorenzo Pellegrini's free-kick with 15 minutes remaining to complete a clinical Roma comeback from going behind to Federico Dimarco's fine first-half strike.
"I hope I can keep scoring goals," Smalling told DAZN after netting his second match-winner of the season.
"We've got a very strong squad this season, and we have big goals we're aiming at."
Jose Mourinho's side, which levelled through a superb Paulo Dybala volley six minutes before halftime, showed it can do it against the big boys with a mature performance which for once didn't finish with wasted chances leaving it wondering what might have been.
Roma are four points behind Napoli in fifth place after a win which also leaves Inter, who dominated early on but fell away, further back in the title race.
Simone Inzaghi's seventh-placed team is eight points off the pace after losing for the fourth time in eight matches, hardly the best preparation for the crucial Champions League visit of Barcelona on Tuesday.
Inter also trail their local rivals AC Milan by five points after two stoppage-time strikes from Fode Ballo-Toure and Rafael Leao snatched a 3-1 win for the champions at Empoli.
Milan, who took the lead through Ante Rebic with 11 minutes remaining, were left reeling when Nedim Bajrami's pinpoint free-kick levelled the scores in the 92nd minute.
But with Empoli still celebrating what they assumed was a hard-earned point, Ballo-Toure put Milan back ahead when he pushed in Rade Krunic's knockdown.
And Leao, who set up Rebic's opener and had been the star performer for Milan, then capped a stunning win by racing through on goal unopposed and classily dinking in the third in the seventh minute of added time.
It was another superb display from Portugal winger Leao, who has scored four goals and set up six more in all competitions this season, an incredible number which makes him the one to watch at Chelsea on Wednesday.
Lazio stay in top 4
Lazio ensured that they would stay in Serie A's top four on Sunday after comfortably beating Spezia 4-0 in Rome.
First half goals from Mattia Zaccagni and boyhood Lazio fan Alessio Romagnoli and a brace from Sergej Milinkovic-Savic at the Stadio Olimpico put the hosts three points behind league leaders Napoli in third.
Maurizio Sarri's team are level on 17 points with AC Milan and second-placed Atalanta after making short work of Spezia, who are four points above the relegation zone, and claiming their third straight league win.
