The Liverpool goalkeeper did not hide his anger after Jacquet turned away from a free-kick and left a hole in the wall.
Liverpool suffered a second successive defeat as Fenerbahce came from behind twice and scored three times from dead-ball situations.
Fenerbahce’s first goal came from a free-kick, the second from a corner and the third from a long throw-in.
Worse followed when Birmingham-born Brown looped a cross into the heart of Liverpool’s box.
Liverpool twice led in a hostile stadium but could not hold the advantage.
Iraola said communication broke down. “It was difficult for me to give instructions and the communication must have been difficult between Cody and Ali.”. “It’s so frustrating because this is a difficult place to play and we were winning twice,” Iraola said. “We knew set pieces were one of the strengths of Fenerbahce,” Iraola said.
