The Catalans fielded a makeshift side given injuries to the likes of Lionel Messi, Xavi and Victor Valdes, though goals from Andres Iniesta, Cesc Fabregas, Alexis Sanchez and Pedro ensured they romped to victory.
Regardless of injuries, Martino insists his side have the depth of talent to win in style in the majority of matches - although he suggested his perception of attractive football could be different to that of certain neutrals.
"We know that in addition to winning, which is most important, we are committed to the spectacle and how we set up," the 50-year-old told reporters after the match.
"I have seen a good Barcelona, but perhaps how I look at beautiful football is different to you. I believe that you can have 20 pretty touches [to score] or you can have three.
"Those missing are very strong, but those who played are very good too. At least half trained with us during the week, so there was no reason not to play a good game.
"We must solve our problems, not complain. With this squad, I will never make excuses."
Martino was particularly impressed with the performances of Neymar and Iniesta in Messi's absence, stating: "Neymar played a strong game despite not scoring. We also have Cesc, Alexis and Sergi Roberto [for the attacking role].
"It's important to have alternatives. It's good to have players who are specialists in their positions, yet adapt to others. Iniesta was the best out there tonight and when you see him, it's clear he can do anything."
