Pellegrino had a spell with Barca as a player.
“Everything is possible in football he said," he said. “When you're faced with such a massive disadvantage you have to try and make your opponent uncomfortable. We worked really hard, things went our way and we won.
Pellegrino said he was surprised that Barcelona didn't create more chances: “We expected them to create more danger from open play but in the end the goal came from a set piece, which is something we need to address."
“I hope the team continues to grow, this will stand us in good stead," he added.
