The 21-year-old midfielder, dubbed the 'Dutch Xavi' in his homeland, has enjoyed a successful season in Holland with his fine form attracting the attention of a whole host of Europe's elite.
Arsenal and Tottenham were reportedly going head-to-head in pursuit of Clasie, but the north London rivals' hopes of landing the Holland international have been dashed following this latest development.
Clasie, who has scored five league goals in 66 matches for Feyenoord, has quelled speculation of an imminent move by committing his long-term future to the club, signing a new contract until 2016.
The new deal should prevent Europe's top clubs from targeting Clasie for now, but if he can maintain his form over the next few seasons, it would come as no surprise to see the likes of Gunners boss Arsene Wenger or Spurs chief Andre Villas-Boas come calling again.
"It means a lot to me to play for Feyenoord," Clasie is quoted as saying by talkSPORT.
"I have played for this club for 14 years now, including two years in the senior team. It has been fantastic and I am really enjoying myself."
Clasie, who made 32 appearances during a successful loan spell with Excelsior, made his Feyenoord debut in 2011 and quickly became a fans favourite, owing to his tenacious approach and passing ability.
The five-times capped Dutch international is now regarded as one of the Eredivisie's top talents, and reported interest in his services is inevitable given his meteoric rise to stardom.
For now, at least, the Arsenal and Tottenham target remains a Feyenoord player, but whether they can hold onto their most prized asset in the long-term remains to be seen.
