NEC Nijmegen technical director Carlos Aalbers admits he has mixed feelings over midfielder John Goossens' proposed move to Swansea in January.
Reports suggest the 23-year-old is poised to join the Premier League club in next month's transfer window after the two sides agreed a fee.
Goossens is out of contract at NEC at the end of the season and the Eredivisie outfit did not want to risk losing him on a free transfer in the summer.
After the Dutchman spurned the club's offer of a contract extension, Aalbers admits selling him for a reasonable price is the next best option.
But the technical chief admits the club will miss the midfielder's talent, telling Omroep Gelderland: "It's a consideration between business and football.
"As technical manager it's a shame but if we sell him now we will receive a transfer fee. At the end of the season we won't.
"We have tried to extend the deal with John, but he was not interested, so this is the best solution for the club.
"Of course it's hard, as we will miss a fantastic player."
