Edin Dzeko found the back of the net with a trademark header, as AS Roma inflicted a second consecutive defeat for title rivals Juventus.
The Bosnian fired home a 79th minute header in a 2-1 victory over the Old Lady, who are without a point after two games.
It was the on-loan Manchester City striker's first goal for his new club, who he will most likely join on a permanent basis at season's end.
Happy for my goal,but even happier for the amazing win and team's great effort #bravoragazzi thank u to all the fans for support

Also featuring in the clash was Arsenal goalkeeper Wojciech Szczesny, who made a tremendous stoppage time save to secure the three points for the Giallorossi.
