Ukraine - Benfica made light work of Dynamo Kiev as Eduardo Salvio and Franco Servi scored on Wednesday for their first win in the Champions League this season.
Goncalo Guedes was brought down by Antunes, allowing Salvio the chance to score from the penalty spot in the ninth minute.
Conceding early disrupted Dynamo's rhythm and the hosts fell further behind in the 55th minute 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.
Meanwhile, Dynamo have only conjured up a single point.
