MORGAN GIBBS-WHITE scored a wonderful goal as Chris Wilder went empty-handed at Bramall Lane.
Billy Sharp was the tormentor of the Middlesbrough boss in the first half as the Blades scored twice in the first two-minute span.
First, the 36-year-old striker created the opening goal for United in the 23rd minute with a run and stretch, and finally, the striker let Sander Berge cross to finish from close range.
He later went home on his own after Gibbs-White stormed out to punish sloppy Boro.
Jack Robinson won number 3 in the 59th minute.
Arsenal loanee Folarin Balogun pulled back a goal after goalkeeper Wes Foderingham howled three minutes later.
But Gibbs-White’s daring heel strike added the ball to The Blades’ victory in the 79th minute.
The Wolves loanee somehow twisted their bodies to fire in Ben Osborn’s cross from the right for his ninth goal in an impressive season.
