Sheffield United secured just their fourth Premier League win of the season to dent Aston Villa's European hopes as David McGoldrick's strike earned a 1-0 win at Bramall Lane
McGoldrick put the Blades in front after 31 minutes when he turned home George Baldock's driven cross, sticking out his leg to divert the ball into the net via the underside of the crossbar
The hosts were reduced to 10 men following VAR review in the second period as Phil Jagielka's challenge on Anwar El Ghazi when the last defender was upgraded to a red card by referee Rob Jones
But Chris Wilder's men held on for a rare three points to close the gap on 17th-placed Newcastle to 12 points with 11 games remaining
 Villa stay in ninth place on 39 points after 25 games
Wilder, whose side ended a four-game losing streak, admitted this week he does not know if he will be Sheffield United manager next season, but his team produced a valiant display, absorbing some early pressure
Aston Villa, in the continued absence of Jack Grealish, were seeking back-to-back wins for the first time since Boxing Day - and they had the game's first chance as Ollie Watkins headed into the path of John McGinn but the midfielder's shot across goal failed to trouble Aaron Ramsdale
But Ramsdale was forced into action after 19 minutes when Anwar El Ghazi slipped Watkins into space down the left channel and his low drive was parried out by the former Bournemouth goalkeeper
 Watkins wanted a penalty moments later when he was sandwiched inside the box by Kean Bryan and Jagielka but referee Jones waved away his protests
Having defended resolutely, the hosts took the lead just after the half-hour mark
 McGoldrick started and finished the move as his raking pass found Baldock on the right
 After the wing-back cut inside, his effort was drifting wide before McGoldrick stretched out a leg to lift the ball into the net via the underside of the bar
It was the 33-year-old's sixth goal in 16 Premier League starts this season and only the third time in 14 home games this campaign that Sheffield United had opened the scoring - but they were so nearly pegged back immediately
Bertrand Traore was found by Ahmed Elmohamady, and the forward escaped Oliver Norwood, Jagielka and Bryan with his weaving run before curling his shot just wide of the post
It was a frustrating opening 45 minutes for Villa, who were faced with the challenge of improving a record of collecting just one point having conceded the first goal this term
The visitors hadn't come back to win a Premier League game since January last season against Watford, but they came within inches of equalising nine minutes into the restart when Watkins directed El Ghazi's cross onto the woodwork
A minute later came the game's major flashpoint as Jagielka was initially shown yellow for hauling down El Ghazi on the counter-attack
 But VAR Graham Scott advised Jones to review the incident via a pitchside monitor, and the match official upgraded the card to red, deeming Jagielka to have been the last defender
Sky Sports' Nick Wright said: "Another game, another instance of VAR controversy
 Jagielka was clumsy but was El Ghazi really away? Or would one of Jagielka's team-mates got back and caught him? There will be plenty of differing views on that one
"Villa failed to make their numerical advantage count, however, as Wilder immediately reverted to a back four
Chances were few and far between but Sheffield United stood defiant
 El Ghazi's cross was headed back across goal by Traore for McGinn to shoot first time but Ethan Ampadu was in the right place to block
Villa continued to press against the disciplined Blades backline, but when Ezri Konsa's low shot was brilliantly kept out by Ramsdale in the final minute of normal time, the Premier League's bottom side had the victory their efforts deserved
Sheffield United boss : "It's a win that was made a little bit more difficult by going down to 10 men but we showed good character
 It was similar to a lot of games we played in the Premier League last year
"We took our moments last season and we didn't make any individual errors, which have basically cost us so many points all season
 If you do this, it allows you to get the kind of results like this which we consistently got last season
"On Phil Jagielka's red card: "He was gone the moment he went over [to the monitor]
 Villa are a great club, but they've had some decisions against us
 I don't think Villa can ever complain about the decisions that have gone against us in our previous three fixtures
 We got on with it and kept the ball out of the back of the net
"He was a long way out
 I still think Bryan is close enough and we had retreating players
 I think it's harsh
 Some of the decisions, not just for us, but for everyone else are head-scratching
 But maybe I've gone past caring
 I even thought [David McGoldrick] was offside given the luck we've had this season!"We showed an unbelievable desire to keep the ball out of the net
 I said to the players I'll celebrate for them tonight
 They have another game on Saturday
 All the beers they might have drunk tonight, I'll do that for them
 I'll give it a good go
 It was everything you want in a performance
 That was a game like 90 per cent of our games last season
"Aston Villa boss : "We found it difficult to provide a decent ball tonight and the one time we did, Ollie [Watkins] ended up hitting the bar
 With all the possession we had in the final third, we needed better quality runs and balls
"For me, we tried to get the goal back within the first five minutes after the sending off rather than being a little bit more patient by dragging them out
"I have no worries about us scoring goals
 If we take our big chances today, we're not having the discussion [of a lack of goals]
 As long as we create big chances in games, that's what I'm interested in
 We did in the first half but we didn't so much in the second period
 When a team goes down to 10 men, you can see them all in front of the 18-yard box and they were hard to break down
"We've had three days in between the games and felt that was enough recovery period to go again
 I felt it would be a game where second balls would be important, and we did that quite well
 There were moments in the first half where we were very good despite maybe not being as crisp on the ball
 We've not taken our chances while they've taken their one opportunity
"Villa lacked quality in front of goal and became frantic as they chased the game in the second period, but this missed opportunity was thanks in large part to Ramsdale's resolute performance, in front of the excellent Bryan and Ampadu
The England U21 international has endured a difficult season since arriving as Dean Henderson's replacement last summer, but a second clean sheet of the campaign was earned through four crucial saves as Villa pursued an equaliser in the closing stages
His quick reflexes to thwart Konsa's firm strike late on keeps Sheffield United's flickering hopes of survival alive
Sheffield United host Southampton in the Premier League on Saturday, live on ; kick-off is at 3pm
