Burnley have sold young Greek striker Dimitris Papadopoulos to Panathinaikos for an undisclosed fee.
There has been plenty of speculation in the Greek media regarding a move for the 21-year-old, but until yesterday no moves had been made by the Athens club.
However, the clubs have reached an agreement, including a fee believed to be around 200,000 for Papadopoulos, who joined Burnley two years ago for 500,000 from Akratitos.
His time at Turf Moor was often disrupted by his commitments to the Greece Under-21 side, where he is considered one of the main players and a striker expected to spearhead their Olympic team.
Last season, the pacy forward scored his first goals in England but failed to establish himself in the starting line-up.
There is also a sell-on clause in the contract that will see Burnley pick up cash from future transfers.
Chesterfield fans have voted in favour of a move to a new purpose-built stadium on the Wheeldon Mill site on the outskirts of the town.
