Trippier made his first start in the win over Arsenal last night since January 12 when he earned a rare start in the FA Cup win over Bromley.
He helped his side earn a vital win with a clean sheet, but he has started just five league games this season and was linked with a move away in the summer and during the recent January window.
The defender was seen to be open to a move away in January but Trippier was reportedly disappointed not to have been allowed to make the move to the Turkish club on loan.
Eddie Howe reportedly wants to keep him at least until the end of the season but it is said that Trippier's morale has been "seriously damaged" by seeing this move blocked.
One reason the move struggled to take off was down to Galatasaray wanting a straight loan for the former Tottenham man, with no buy option, which may have been crucial.
There are still another five days left in the window in Turkey at the time of writing, with their winter window beginning on January 13 and ending on February 11, meaning there is still time for a renegotiation.
Howe was forced to comment on Trippier's future in recent days, especially given the speculation over his desire to exit the club.
"I'm surprised by a lot of the stories that have come out," Howe told reporters. "(He's) a valuable member of the squad.
"His professionalism has been first-class. I'm not really sure where this has come from. His leadership skills, his ability with the ball, his assist record, everything he brings to the group we definitely want here."
