Wolves boss Nuno paid tribute to Bristol City after their FA Cup triumph.
Ivan Cavaleiro's first half finish was enough to seal Wolves' passage through to the quarter finals for the first time since 2003.
Nuno said: "They have a lot of quality, we were in the Championship last season, and sometimes, with all respect, some teams in the Championship are as hard as Premier League teams. We looked at our opponents, Bristol City are a very good team with a very good manager, who has his ideas, and he pushes the team to its limits.
“The enormous achievement we made was today. Now we have to make the next step, rest well and prepare for the game against Bournemouth. Let's see the draw and we'll think about it."
