However, Ten Hag wants to take a look at Garner with the prospect of adding him to his squad for next season.
Speaking after Forest's promotion, Garner said: "Before I went on loan, there were questions of am I physically ready to compete, to play first-team football, and I believe that I've shown that this season.
"Not only playing a lot of games but how I've held my own in such a tough league and men's football, you know. I think I've shown that.
"I've not spoken to [Ten Hag] yet. I literally came from the play-off final straight to England, so I've had no rest, no break, just been football, football so I've not spoken to anybody at the club. It's time for rest now and I'm not sure what the future holds."
