BURNLEY carried on from where they left off at the Valley tonight with an impressive first half performance at Turf Moor that sees them a goal ahead at the interval.
Owen Coyle named the same starting 11 to the one that came away from London with the three points at the weekend.
And, after a balanced opening, the Clarets began to dominate.
That it was the in-form Robbie Blake who provided the inspiration came as no surprise.
He was a constant menace again and his clever pass sent defender Graham Alexander clear down the right flank in the 18th minute.
Alexander slipped in a neat pass to Wade Elliott and his low whipped cross was crying out to be smashed into the net from six yards.
Andy Gray, with 13 goals to his name already this season, contrived to completely mis-kick the ball and Leicester breathed again.
The respite did not last long, however, as a delightful flowing move cut the Foxes to pieces and ultimately led to the opening goal.
Elliott drifted in from the right flank, and advanced deep into Leicester territory before finding Chris McCann with a cute pass.
The unmarked McCann showed outstanding vision to supply Blake - unmarked on left-hand side of the visitors' 18-yard box.
Blake pulled the trigger to round off a brilliant move but his left-foot strike was deflected out for a corner by Alan Maybury's last-ditch intervention.
From the resulting corner, though, Blake's quick thinking led to him collecting possession and reaching the byline before whipping in a low cross which Unsworth dispatched from six yards.
It was his first goal since scoring the penalty that kept Wigan in the Barclays Premier League at the expense of Sheffield United on the final day of last season.
Blake threatened a second in the 25th minute after more intricate footwork gave him a shooting chance from 20 yards, but Patrick Kisnorbo made a vital block.
