The Coca-Cola Championship club unveiled the Dutchman as their new head coach last week but it has since emerged he has only signed a pre-contract agreement with Saints and is still contracted to Helmond.
Managing director Mario Captein told www.voetbalprimeur.nl: "I clearly told everyone the week before that Helmond Sport would not co-operate in any transfer of our coach. We were not and are not interested in a transfer fee. I told Jan he has a contract and we keep him to that contract."
