Sheffield United closed in on the Premier League's top four after Billy Sharp's first-half header and Dean Henderson's superb late save secured a 1-0 victory over bottom side Norwich at Bramall Lane
After Teemu Pukki struck the upright from close range in the 14th minute, the Blades took control and Sharp headed home John Lundstram's brilliant cross in the 36th minute for his third in four games
It proved to be the only goal of the game but only because of a remarkable piece of goalkeeping from Henderson to deny Ben Godfrey, Mario Vrancic and Josep Drmic from close range as the Blades stayed firmly in the hunt for European qualification
Chris Wilder's side, who are up to sixth for a few hours at least, find themselves two points behind fourth-placed Chelsea, who face Everton, live on  on 
Meanwhile, Norwich's chances of survival take a huge dent with Daniel Farke's team still six points adrift of safety with nine matches remaining
Sheffield United started brightly and Oli McBurnie should have done better after being picked out by Sharp, but the striker's header was straight at Tim Krul, who tipped the ball over the crossbar
However, Norwich had an even better chance when Ondrej Duda's far-post cross was headed back across goal by Pukki but in attempting to clear the danger George Baldock headed the ball straight back to the Finland international, whose shot from inside the six-yard box struck the upright
The Blades started to dominate the game and bombarded the Norwich penalty area with crosses, and they would have had the lead in the 33rd minute but for Kenny McLean's last-ditch block to keep out Jack O'Connell's goal bound strike
They did not have long to wait for the breakthrough though, as three minutes later Sharp popped up to head past Krul after being picked out by Lundstram's inch-perfect cross from the right
Norwich were on the ropes and Wilder's side could have extended their lead just before the break as Sharp returned the favour to Lundstram, but the midfielder's shot was straight at Krul, who made a comfortable save
Norwich made a change at the break with Josip Drmic replacing Todd Cantwell and the substitute got straight into the action as he rose above Chris Basham to send a header wide
At the other end, Basham produced an excellent piece of skill, lifting the ball over McLean but the defender could not test Krul, steering his shot over the crossbar
Then came Henderson's moment
 He was called into action with 11 minutes remaining and he produced a world-class multiple save to show why he is so highly regarded
Emiliano Buendia's corner was met with a powerful header by Ben Godfrey but, under pressure from Mario Vrancic, Henderson got down low to his left to claw the ball away, before showing good reactions to keep out Vrancic's effort right on his own goalline
The rebound then fell to Drmic and he looked almost certain to equalise for the visitors, but Henderson was in the way once again before a combination of David McGoldrick and the crossbar denied Drmic again
Norwich were inches from an equaliser and Jamal Lewis was next to be denied by Henderson, who palmed the full-back's volley away to safety as the Blades held on for what could prove to be a crucial three points
The Sheffield United goalkeeper was largely untested against Norwich, but when finally called upon 11 minutes from time he delivered
The on-loan Manchester United goalkeeper produced a world-class piece of goalkeeping to ensure victory for his side, showing in the process why he is being spoken about as a potential England number one for this summer's European Championships
The 22-year-old has kept 10 clean sheets in his 27 Premier League games this season - becoming the 11th 'keeper to reach double figures under the age of 23, and the fourth English 'keeper to do so after Joe Hart, Scott Carson and Jack Butland
: "He's not had a great deal to do and then he's made some important saves, but that's what the best ones do
 Dean, in my opinion, is one of the best
"He has had a fantastic season and he has a big 10 games to play and hopefully some more cup games and I would be very, very surprised if he is not named in the upcoming England squad
 I'm sure he will be and I'm sure he will get an opportunity in one of the two games as well
 He's got everything to play for
"He has matured and his concentration levels are fantastic, as we saw today
 He's got a huge desire to take his game to the very top
 He's a confident boy, he's not shy, but he backs it up
": "The stats are there and the league table is there, we can't shy away from it
 There's some great games to come for us, starting with a huge game at Newcastle next week
": "We give him lots of trust and he knows he has a head coach who backs him and trusts him
 He had a good situation today and it is one where he normally scores but even such an experienced player has dry spells and suffers a bit with confidence
"Sometimes there are times where you just have to watch the ball and it goes in, other times from four or five yards out you can't even get it over the line
 Teemu needs a goal from open play and sometimes what you need in this situation is a dirty goal, maybe a ball deflects in off him or the centre-back hits the ball against his back and it flies in
 I hope he finds a finish pretty soon
"Sheffield United are back in action next Saturday - March 14 - when they travel to St James' Park to face Newcastle; kick-off 3pm
Norwich also play at 3pm next Saturday and they host Southampton at Carrow Road
