Sheffield United produced an acceptable display throughout but could be accused of lacklustre in defence; allowing Brian Laws Burnley to find the net three times.
Though the Blades could have seen half-time as early leaders after what can only be described as great saved from shot stopper Brian Jensen to deny a few great chances.
Firstly, with two minutes of the start Johannes Ertrl saw his goal bound effort palmed over the crossbar by the Danish keeper.
Mark Yeates also saw a brace of chances denied; two free-kicks almost found the net when his first strike was equally met by Jensen and his second lashed against the foot of the post.
In an entertaining fixture at Bramall Lane the Blades came from two goals down to draw level at three-all. United had plenty of chances throughout the game.
All six goals came in the second when the visitors went two goals to the good; within minutes of the re-start United were in attack with Ertl again denied by Jensen.
Soon followed the goals with Dean Marney (49 minutes) heading the ball home past Steve Simonsen and when five minutes later Chris Iwelumo was tripped in the box by de Laet it was virtually game over when Chris Eagles converted the spot kick.
However they were given a lifeline when Leon Cort tumbled at the back to all Daniel Bogdanovic (57) the opportunities to seal the ball close to goal and neatly finish past Jensen.
The Blades made the score level when good work from Yeates on the left flank found substitute Matthew Lowton (82) who with the aid of a slight deflection found the back of the net.
Not to be out done the Clarets bounced back and with 30 seconds left on the clock Jay Rodiguez found himself in plenty of space to fire the ball home. The win looked in the bag for the visitors who brought a healthy following but there was to be a twist in this story...
... The officials added five minutes of extra play to the game and this allowed United; three minutes into it to have the last say; Mark Yeates marched up the field, he weaved around the defence before firing past Jensen in the Burnley net!
