Wolves played away from their Molineux home on Saturday afternoon, securing a 2-1 win in west London against Brentford.
Ruben Neves scored the winner for Bruno Lage's men, who continue their push for a European spot.
Their next game at Molineux will be in February when they take on Norwich City in the FA Cup.
Lage said following the win at Brentford: "It was a strange first half and the two breaks didn't help the game's rhythm.
"But we did very well in the second half, the break helped us and we came with that will to win the game.
"We started well and scored a goal and then they scored, they are very good from set pieces.
"But we came again and in the end we scored goals and I'm happy because we came with the personality to play our game with the consistency I have been asking from them.
"It's very hard to play against this team, especially at home. I am happy because of the quality of our work."
