Dutch international Siem de Jong has prolonged his stay with AFC Ajax after signing a contract extension keeping him at the Amsterdam club until June 2015.
The new deal adds two years to the contract of a player who had a huge part in Ajax's 2010/11 Eredivisie title-winning campaign – attacking midfielder De Jong scored 12 goals in 32 games. The 22-year-old also made his international debut against Ukraine last August.
"My goal is to win the championship again and to contribute as much as possible to the team," said De Jong, who joined the Godenzonen from De Graafschap in September 2007 and has made 86 league appearances in four seasons at the Amsterdam ArenA. "I am happy to extend my contract because I really like it here. Ajax are good for my development."
Ajax enter this season's UEFA Champions League at the group stage with the draw taking place on 25 August in Monaco.
