The boss praised his player's mature performance, singling out their ability to up the intensity throughout the 90 minutes.
"I liked that we grew in intensity and showed more determination as the game went on," he said. "This is about building momentum and gaining positions. It's a long-distance race and you have to go little by little."
He added: "It was a very intense match, from the first minute to the last. Valencia are a good team, they have players who create a lot of danger. In general, it was a hard-fought and entertaining game. Thankfully we've come through it with three more points."
