The visitors found it tough going at San Mames and created very few chances. Lionel Messi hit the crossbar in the first half but that was about as good as it got.
Valverde offered his view on the match after the final whistle.
“We couldn’t really get going in the last third of the field. We thought the game would have more rhythm and it just didn’t turn out like that,” he said.
“We’re just responsible for what we do and I think in general, we should have created more than we did.
“They pressed us high, but we did get through that and we did get through to their box.
“But then that left us exposed to counter-attacks and they created problems.”
