A brace from Lionel Messi and one from Zlatan Ibrahimovic secured a 1-3 away win to Barca.
Guardiola told Marca: “Deportivo only had one real chance.
“We did not deserve to concede the goal before half-time. I am very happy with the second half performance.
“Deportivo did well to restrict us down the middle. Pedro’s instance opened up the field more.
“We dominated the game in a difficult stadium.”
He added: “They are a very well organized team.
“I imagine that the injuries to Riki and Lassad hurt them, but they still have a very good team. Their president gives confidence to the coaches.
“Filipe Luis is a great player, as are Guardado and Manuel Pablo.
“It is not a coincidence that they are so high up in the table.”
