League One outfit Chesterfield have completed the permanent signing of Sheffield Wednesday striker Emmanuel Dieseruvwe.
The 19-year-old initially arrived at the Proact Stadium in January on a month's loan, but has now been handed a 18-month contract with the Spireites.
Manager Paul Cook told the club's official website: "We're delighted to have Mani with us permanently now. He has power and pace and that's exactly what a lot of teams are looking for to play in today's game.
"Mani's shown great signs in training and we're really excited to see what he'll be able to do with our team going forwards."
Dieseruvwe has not played for Wednesday, instead making his Football League debut for previous loan club Fleetwood Town in November 2013.
