Sheffield United manager Chris Wilder: "I have to say, Dean Smith and John Terry were in the tunnel clapping our players because they recognise our players' performance today. That's a class act and people won't see that but I want to mention it.
"It was a proper second-half performance. It was a cagey first half and I don't think we had many big opportunities, but I felt it was coming before half-time and we stepped it up in the second half.
"We rode our luck with Jack Grealish missing the penalty, but I think the right result has happened today."
Aston Villa boss Dean Smith: "Our overall performance wasn't what I wanted from this group of players. We didn't cause them enough problems.
"The second goal was a bit of a killer but they probably deserved the win on the day.
"The players need lifting, we've lost three games on the spin but I just said to the players that a few games ago we were walking off the pitch at Old Trafford a couple of days after beating Newcastle and we should have got a win at Manchester United."
