Crystal Palace manager Roy Hodgson, speaking to Sky Sports: "The goal was unfortunate because Guaita's done so well for us this season. He's made fantastic saves to keep us in games and get us three points at times.
"It's disappointing that he's going to bear the brunt of the criticism. Everyone who watches the game tonight will say it was the goalkeeper's fault. I'm sad for him because he doesn't deserve that."
On referee Andy Madley: "We thought George Baldock should have been red carded, but I don't want to pick the referee's decisions here and there. If we'd been given a red card and they'd been able to play on with 11 men after Baldock's challenge, I'd be perfectly entitled to stand here and say the referee hasn't done us any favours."
Sheffield United manager Chris Wilder: "It's a huge result today. We were up against some really good players but the team kept their discipline and shape.
"We were lucky with the goal, but I thought we were good value for the win. We're delighted to add another three points to the number we have already.
"Palace have a habit of feeling their way into the game and coming on strongly in the second half, but they started very well. I felt we stuck in the game and managed to get a very valuable three points."
