Kiev: Eduardo Salvio converted a penalty and Franco Servi also scored as Benfica beat Dynamo Kiev 2-0 on Wednesday for a first win in the Champions League this season.
Gonçalo Guedes was brought down by Antunes, allowing Salvio the chance to score from the spot in the ninth minute.
Conceding early disrupted Dynamo's rhythm and the hosts fell further behind in the 55th, when Servi scored at the second attempt after his first effort struck his own player, Kostas Mitroglou.
Benfica moved up to third in Group C, a point behind Besiktas and two behind Napoli after three games. Dynamo has one point.
