Sheffield United midfielder Tom Davies told Sky Sports:
"It's obviously an amazing feeling. I just wanted to come back and show something and I managed to do that.
"The manager hasn't rushed me back, he's let me recover. I just said a massive thanks to him.
"It's an amazing club, so we just want to see where the season is going."
Sheffield United boss Chris Wilder told Sky Sports:
"The last 20 to 25 minutes, there was only one team that looked like winning in my opinion. That last 25 minutes were outstanding and the fitness levels were amazing.
"We needed to control the middle of the park and, when we did, I thought we were good. We still made poor decisions. When you make poor decisions, it becomes a basketball game.
"I always felt there was a winner inside us and I never felt like they were going to score."
On Davies returning from injury to score the winner: "No shortcuts, Tom's quality is to be seen by everybody.
"When you get moments like that, those kinds of stories in football, it puts a smile on your face."
Sunderland boss Regis Le Bris told BBC Radio Newcastle:
"We are frustrated at the end of the game, because we demonstrated a good level against one of the strongest teams in the league.
"We controlled the game and we were dominant but we didn't score.
"I hope we can keep this mindset because we have a good level, but we have to find some details to change the dynamic.
"We created chances, so it's a shame. We did well but it was not enough."
