Sporting Lisbon have signed forward Ricky van Wolfswinkel from Utrecht on a five-year contract for a transfer fee of €5.4 million.
The Portuguese stock market commission (CMVM) made the announcement on Friday that they have been informed by Sporting about the deal.
The CMVM further added that the release clause of the 22-year-old is €22m. His contract at Utrecht was due to run out in June 2013.
Van Wolfswinkel joined the Dutch side in 2009 from Vitesse and established himself as one of the better forwards in the Eredivisie. The Netherlands international scored 15 goals and provided four assists in 29 league matches in the 2010-11 campaign and also netted seven times in six Europa League fixtures.
Sporting finished third in the Portuguese league in the 2010-11 season and will enter the play-off round of the Europa League next campaign.
