Primera Liga side Espanyol had been hoping to secure the 29-year-old former AZ Alkmaar forward on a loan deal for the rest of the campaign, but PSV technical manager Stan Valckx is unwilling to let Koevermans leave.
He told De Telegraaf: "Espanyol can spare themselves the trouble of contacting us again. We are not letting anyone go anywhere. And we certainly will not be letting our top scorer leave."
