The loaned out Rangers striker is due back at Ibrox next week.
Tommy Wright claims he has been unable to get hold of Michael O'Halloran's agent ahead of the Rangers player's return to Ibrox.
O'Halloran is due to play the final game of his St Johnstone loan spell on Saturday, and Saints boss Wright says nothing has changed since last week's revelation that Rangers are planning to bring back the five-goal forward.
The 54-year-old said, as quoted by Sky Sports [live blog entry: 12:30]: "There's no change. This will be his last game in the current agreement.
"The hope from my point of view is that we can get him back but I have tried to get hold of his agent over the last few days and can't get him. So it's something we will have to discuss.
"I have told my chairman I would like him back and if there is an opportunity I would like to think that my chairman could make that happen for me."
O'Halloran moved to Rangers from St Johnstone in January 2016, and helped the Ibrox side to the Championship title four months later.
He only made six league starts last season, however, and was banished by Pedro Caixinha after the Portuguese coach's appointment earlier this year.
But with Caixinha having since departed and Kenny Miller facing a lengthy spell on the sidelines, it is understandable that Rangers' new boss Graeme Murty would want to take a closer look at O'Halloran this winter.
