Tommy Wright says the winger is going nowhere.
Glasgow Rangers are hopeful to tie up some transfers before the end of the season, as they look to fend off Hibernian in the race for the Scottish Championship title.
The speedy wide man has been in fantastic form in the Scottish Premiership this term and the fantastic football he has been playing will not have gone unnoticed among the Rangers faithful.
However, getting hold of O'Halloran is proving increasingly difficult.
Rangers have already had two bids for the player rejected by the club and it seems O'Halloran will continue to play his football at McDiarmid Park.
The Saints boss Tommy Wright has told The Courier this weekend that a third bid is expected from Rangers - but that it will not be accepted:
“The chairman informed me that Rangers had come in with one bid and then another. Both have been rejected and that’s the state of play.
“The bids have done nothing to interest the chairman. We think we know what Michael is worth and that is the same with any of our players.
“We can’t stop bids coming in from clubs but we aren’t encouraging offers for Michael. We still want to hold onto him. Nothing has changed."
O'Halloran has played 23 times this season and his electric pace and power have made him a real threat in the Scottish top-flight.
The 25-year-old has previously played for Bolton Wanderers and other English Football League sides on loan and Rangers would represent a massive move for the player.
But with the Perth side standing firm it looks like Mark Warburton might just miss out on the player.
