Rangers captain David Weir believes the Old Firm's stuttering start to the season is giving the rest of the SPL hope of taking top spot.
The defender said: "If we don't stop dropping points then I'm sure it will encourage everybody else if they see it is possible to beat the Old Firm.
"We need to put a run together where we are winning games as we have not done that for any length of time.
"There are other teams that will be looking at that and getting encouragement. The league is wide open at the minute."
The defeat at Pittodrie was only Walter Smith's side first loss on their travels this season but Weir believes it was only a matter of time before the Gers were beaten away from home.
He added: "There has been a trend towards slow starts away from home. We hadn't been beaten until this match but we haven't been playing well enough.
"Perhaps we got away with it a couple of times at St Johnstone and Hearts but against Aberdeen we probably got what we deserved, although we had the majority of the game and the majority of the possession.
"I don't think we did enough to win. We never started well and we showed a lack of composure all through the game."
