Recent reports had suggested that the Red Devils were prepared to part with the 24-year-old, who has made just three Premier League appearances since his switch from Vitesse Arnhem last summer.
However, the Dutchman has claimed that the Man United coaching staff view him as a successor to fellow left-back Patrice Evra.
"I'm doing very well and the club don't want to sell me," Buttner told Omroep Gelderland.
"Manchester United see me as a successor for Evra, so they won't loan me out to another club. After this, I am aiming for a successful pre-season ahead of the new season."
Buttner has made 11 outings for United in all competitions.
