Walker-Peters has struggled for game time since his arrival but Hasenhuttl made it clear that he's yet to make his mind up about the defender.
“I've not decided yet," Saints' boss explained.
“He will stay with us to the end of the season with us and we have now 8 games in the short term so it's quite likely he can start one game or two games or whatever.
“It's important that we trust every player who is with us and I do this - and when he gets the chance he will make a good game."
"Same as Kyle, I haven't decided yet (about making a permanent move)," Hasenhuttl added.
"Let them play the last eight games, let me look how far he is in his development, how quick he takes it and we have time to decide it.
"Everybody should get the chance to show up in the last games."
