Iago Falque's brace handed Joe Hart's Torino a home victory over Roma for the first time since 1990 as Sinisa Mihajlovic's side prevailed 3-1 in Serie A.
Falque left Roma in the summer for a season-long loan deal with Torino, and wasted little time in making his parent club pay for farming him out.
Fit-again Torino hitman Andrea Belotti struck his fifth league goal of the campaign on his first start since a thigh problem, while Francesco Totti converted a penalty for Roma - two days shy of his 40th birthday.
England stopper Hart revelled in thwarting former Manchester City team-mate Edin Dzeko at every turn at the Stadio Olimpico as Torino claimed their second win of the league campaign.
