Former striker Rory Loy thinks "serious questions" are starting to be asked of head coach Danny Rohl after Rangers failed to beat a depleted Celtic side in last weekend's Scottish Cup quarter-final.
Rangers had 24 shots and almost 60% possession over the 120 minutes at Ibrox, while Celtic had one shot and still took the tie to a shootout where they converted all their penalties as Rohl's side missed two.
That cup exit followed Rangers squandering a two-goal lead to draw at home to Celtic in the Premiership, where the Ibrox side's title challenge has faltered with a run of two wins in the past six league games.
"I don't think he's under serious pressure at this moment in time," Loy told the BBC’s Scottish Football podcast.
"But I think serious questions will be asked of Danny Rohl as to how they didn't manage to beat Celtic, given the possession and dominance they had.
"His substitutions were questionable and serious questions will start to be asked about his in-game decisions.
"And there's not a lot of time in Glasgow between serious questions being asked about decisions to being under serious pressure. Because if you continue to make the wrong decisions and drop points, then the pressure mounts quickly.
"Some of the substitutions on Sunday baffled me, like Mikey Moore coming off. I know he looked a little bit tired, a little bit leggy, but he was the best player in the second half in a creative sense.
"Tochi Chukwuani should have started the game. When he came on I thought he was Rangers' best player in terms of getting on the ball and actually calming things down.
"At this moment in time, no, I don't think Rohl's under pressure for his job or anything like that, but that can change quickly."
