Edin Dzeko marked his first appearance for Roma with a brace in an enthralling 6-4 friendly victory over Sevilla on Friday.
Bosnia-Herzegovina striker Dzeko, who joined the Serie A club from Manchester City earlier this week, netted twice in the first half at Stadio Olimpico.
His goals helped Roma on their way to a 6-0 lead, but Sevilla once again showed their fighting qualities to threaten what would have been a remarkable comeback.
Unai Emery's men trailed Barcelona 4-1 in Tuesday's UEFA Super Cup before pulling it back to 4-4 and eventually losing in extra-time.
The Liga side were up against it again, Dzeko opening the scoring with a thumping near-post shot in the fourth minute and the striker rounding off a wonderful team move to make it 3-0 shortly before the break, after Vasilis Torosidis had also scored.
Dzeko turned provider for Radja Nainggolan to make it 4-0 on the stroke of half-time, before transfer-window recruit Mohamed Salah got in on the act in the second half and veteran captain Francesco Totti added a sixth from the penalty spot in the 63rd minute.
Denis Suarez completed a fine solo effort for what appeared a scant consolation with 20 minutes remaining, but Jose Antonio Reyes – scorer against Barca – further reduced the deficit when he side-footed in Kevin Gameiro's assist.
Suarez was proving a menace and he set up Coke for Sevilla's third, before scoring his second four minutes from time.
