Hammarby are weighing up a potential move for Juan Castillo as they continue their search for a new left-back. The 25-year-old Dominican Republic international, capped 5 times and currently at relegated Eredivisie side RKC Waalwijk, is valued at around €500K by Transfermarkt. Two weeks ago, Viborg tested the waters with a €200K offer, but Hammarby could step in if their number one target cannot be secured. Castillo, who came through the academies of Ajax and Chelsea, is seen as a strong alternative option for the Stockholm club.
