Edin Dzeko bagged a brace in the 10-1 victory over local side Trastevere, with Gianluca Mancini making his debut in a Roma jersey.
Paulo Fonseca continued to use a 4-2-3-1 formation, with Alessandro Florenzi either in a supporting trident or pulled back to midfield.
Inter transfer target Dzeko nodded in a Cengiz Under corner, followed quickly by a trademark Aleksandar Kolarov free kick.
Under was on target himself, then Mirko Antonucci scored before Dzeko added his second on a Rick Karsdorp assist.
Trastevere surprisingly managed to find the back of the net before half-time on the counter-attack.
Bryan Cristante’s daisy-cutter, Christian D’Urso and Patrik Schick were on target, but in the final stages Leonardo Spinazzola set up both Diego Perotti and Gregoire Defrel.
Former Atalanta defender Mancini made his Roma debut for the final 27 minutes.
