Heerenveen have announced the sale of defender Gianni Zuiverloon to Premier League new boys West Brom.
Heerenveen announced on their official website that Zuiverloon has signed a three-year contract.
Zuiverloon, 21, is a Holland Under-21 international who scored the winning penalty in a semi-final shoot-out against England at last year's UEFA European Under-21 Championship.
'On the one hand I find it a pity that I must leave a club like Heerenveen, but this is a nice next step in my career,' Zuiverloon told De Telegraaf newspaper.
'I have been there already and looked around and the club have made a big impression on me. Tomorrow I will be presented to my team-mates and I will be on the training pitch as soon as possible.'
West Brom have already signed striker Roman Bednar and midfielder Kim Do-Heon this summer.
