Craig Moore believes Michael Beale is in a "tough situation" after a nightmare week for Rangers.
The Govan outfit crashed out of the Champions League and were also beaten by Celtic in the first derby fixture of the season.
Pressure is now mounting on Beale and Moore believes it will be hard to turn the situation around after this week's losses.
He told Sky Sports: “It’s a tough situation. Once you get the swell of support against you here then it could be very difficult to come back from.
“I was at the game yesterday and coming out of the stadium there was a lot of supporters really unhappy with the performance, situation and selections. He needs a near perfect run to turn this around.
“Michael Beale is a smart man, he’s a good man but he knows the expectations and what he needs to achieve. That’s also on the players.”
Kyogo Furuhashi netted the winning goal for Celtic at Ibrox yesterday and Brendan Rodgers' side were by far the better team over the course of the 90 minutes.
On the match itself, Moore added: "Over the course of the 90 minutes did they create enough in terms of opportunities to win the match? I would say no.
"I don't think they used the fans and the energy that was there early. They allowed Celtic into the game.
"The concerning thing was that Celtic were nowhere near full strength, that was clear. Rangers were virtually at full strength at home.
"It was a game with a lot of disappointment from the manager, most importantly from the supporters. It wasn't good enough."
