Jeffrey Bruma has agreed a new one-year contract extension at Dutch Champions PSV Eindhoven which will now run until the summer of 2018.
The former Chelsea defender joined PSV in 2013 with a buy-back clause inserted but the new deal means the Blues no longer have an option of bringing back the 24-year-old on the agreed price,
The ball-playing centre-back has become an integral part of Phillip Cocu's side and the Netherlands after leaving Premier League champions in order to game first-team football.
"It is clear that we have a mutual confidence in one another," Bruma told the club's official website.
"This is my third season. On my arrival we expressed goals together, all of which have come true so far. We have become champions and I have become an international.
"With this new contract I'm showing that I'm happy here. This contract renewal shows the relationship between myself and the club is very good.
"Of course, things can always change in football, but I will not leave PSV for just any club."
