Wolves have advanced to the Europa League group-stage after beating Torino on Thursday night.
Goals from Raul Jimenez and Leandro Dendoncker sealed a 5-3 aggregate victory for the Premier League side.
Andrea Belotti levelled the scores for Torino but it wasn't enough to overturn a 3-2 deficit from the first leg.
Speaking after the game, Nuno said: "It's fantastic, isn't it? It's the work that started in the Championship two years ago, and then it's building and building.
"What these boys did is fantastic. It's a small squad and they deserve a lot of credit along with the staff and people behind the scenes.
"It's very important for us. It's massive. Massive."
