Eusebio Di Francesco rued Roma's missed chances and heralded Barcelona goalkeeper Marc-Andre Ter Stegen after a "harsh" 4-1 Champions League defeat at Camp Nou.
Roma appeared to be containing the hosts well until Daniele De Rossi netted a spectacular own goal to undo the Serie A side's hard work.
Di Francesco's men still had their chances, though, and could have at least been level before Barca scored twice in quick succession to move 3-0 in front and seemingly out of sight.
Again Roma rallied and Edin Dzeko scored, but Luis Suarez responded and the scoreline makes for difficult reading for Di Francesco and his players.
