Wesley Verhoek looks set to join Nottingham Forest after the Championship club agreed an undisclosed fee with ADO Den Haag.
The 24-year old Dutch winger has been a target for a number of British clubs this summer and it now seems as though he will join Forest after he passes a medical and agrees personal terms.
Boro boss Steve McClaren knows Verhoek from his time in the Dutch Eredivisie as FC Twente manager and is on the verge of securing services for his promotion chase.
