Rangers hero Kris Boyd has declared that "time is running out" for Michael Beale at Ibrox.
The Light Blues' recent defeat to Celtic means they sit third in the Scottish Premiership after four games.
And the former Scotland international feels the 43-year-old could be on borrowed time in Govan.
He wrote in the Scottish Sun: "Sunday was the most toxic I’ve ever heard Ibrox.
"It was worse than the final dark days under former flop boss Paul Le Guen. I experienced it as a player then and it wasn’t pleasant.
"But the weekend felt like a notch up with punters snapping after yet another feeble defeat.
"To be honest you can hardly blame them. They have shelled out fortunes to follow their team and help fund Michael Beale’s ambitious rebuild.
"And on the evidence so far this season they are being severely short-changed. Four points behind after four games and out of the Champions League is not where Rangers wanted to be.
"There is little margin for error now for Beale and his new-look squad going forward.
"Time is fast running out for the Gers boss."
Meanwhile, Rangers defender Borna Barisic's injury has been described as "nothing serious" by Croatia manager Zlatko Dalic.
The 30-year-old missed the recent defeat to Celtic after pulling up in the second leg of the Ibrox side's Champions League playoff tie against PSV Eindhoven.
Prior to the loss against the Parkhead side, Light Blues boss Michael Beale had said the left-back would make the fixture but he then failed a fitness test on the morning of the game.
However, Barisic seems to have recovered in time for international duty.
Dalic said: "Borna Barisic has had an injury, but the tests we did on him showed that it was nothing serious and he is fit and available for the games.
"He will be fine. We don't have much time to train and prepare because the games come up very fast.
"We know what we can do and we will show it."
