Adama Traore insisted Wolves have rediscovered their pack mentality after victory against Leeds.
Nuno Espirito Santo's side climbed to 11th in the Premier League following Friday's 1-0 win at Molineux.
Traore's second-half strike came back off the crossbar and hit goalkeeper Illan Meslier before rolling over the line.
It was the first time since October that Wolves have recorded back-to-back top-flight wins and they are now unbeaten in four.
"This character shows how tough we work through the 90 minutes," Traore told the club's website. "The strikers, the midfielders, the defenders, I think that character is important, back with that feeling we are a pack, that is the mentality.
"Also, Nuno gets to the team and this is the mentality that we have to follow and this is how we have to do it.
"We'd been working so hard through the game for 90 minutes. We know how Leeds play and also we know against any team they can score.
"So a clean sheet here at home and back-to-back wins are very important to us."
Defeat was harsh on Leeds, who saw Wolves leapfrog them in the table, and Patrick Bamford had a goal disallowed by a narrow offside call.
Mateusz Klich hit a post in the first half while Wolves goalkeeper Rui Patricio twice denied Liam Cooper after the break.
"It was a performance where all the boys were digging it out and we pushed until the very end," Leeds forward Tyler Roberts told the club's website.
"I thought it was a very high-pressured game, both teams were working very hard but it just didn't fall our way.
"It just wasn't to be. The goal they scored was unfortunate for us.
"It was a good run but it was a piece of luck that it comes off the bar, hits the goalkeeper and goes in.
"We bounced back well and pushed to the very end. We'll take the positives, rest up and go again on Tuesday (against Southampton)."
