Russell Martin believes Joel Piroe has regained a "spark" during his time out of action due to suspension.
The Dutchman was banned for three matches as a result of the red card he was shown during Swansea City's 4-0 loss to Burnley at Turf Moor earlier this month. It meant he missed his side's Championship matches against Reading, Cardiff City and Bristol City - with Martin's men claiming seven of the nine points on offer without their top scorer.
He is available for the Swans' clash with Preston North End at Deepdale on Tuesday night, and ahead of the contest in Lancashire, Martin revealed the striker has been hitting peak levels in training ahead of his return to action.
