The midfielder is not impressed by the Portuguese side despite them holding a 1-0 lead from the first leg of their Champions League last-16 match
Borussia Dortmund midfielder Gonzalo Castro has no doubt his team-mates are superior to Benfica despite having to overturn a 1-0 deficit in the second leg of the Champions League last-16 tie.
Pierre-Emerick Aubameyang had a penalty saved after Kostas Mitroglou scored the only goal, and Benfica goalkeeper Ederson turned in further heroics to preserve a slender advantage for Rui Vitoria's men.
Nevertheless, Castro is confident Dortmund are fully in control of their own destiny heading into Wednesday's return at Signal Iduna Park.
