Burnley’s return to Bramall Lane was not a happy one as they were blown away by three first-half goals in a one-sided Roses battle.
Midfield men John Lundstram – who scored his second and third goals in the Premier League – and John Fleck did the damage as the Clarets were subjected to a third straight defeat.
Sean Dyche’s men had no way back after conceding twice just before the break to extend their winless away record.
And while they improved in the second half, a buoyant Sheffield United side always had plenty in hand in securing a second successive home win which lifted them into the top six.
