A former Ajax captain, Siem is an attacking midfielder who joined the Magpies in July 2014 - following in the footsteps of brother and fellow Netherlands international, Luuk de Jong
Born in Switzerland to Dutch parents who played professional volleyball, Siem came through the youth system at De Graafschap and then Ajax before making his senior debut for the Amsterdam club in September 2007.
After almost 250 appearances and four Eredivisie titles with Ajax, Siem signed for Newcastle United and he scored in the club’s opening two pre-season fixtures ahead of the 2014/15 campaign against Oldham Athletic and Sydney FC.
Despite showing flashes of his technical brilliance since, his time on Tyneside has been hampered by long-term injuries and he joined PSV Eindhoven on loan in August 2016 - taking up an opportunity to play alongside his brother Luuk.
Siem made his international debut for Holland against Ukraine in August 2010.
