Rangers manager Derek McInnes admits the squad are "all going to feel pretty miserable" until they turn a corner.
The club are reeling from a penalty shoot-out defeat against Jablonec in the Czech Republic on Thursday night, which means they will not play European football this season for the first time since 2017.
The defeat marks a low point for the club, not dissimilar to the humiliation suffered at the hands of Club Brugge in Champions League qualifying at the same stage last season.
They have won just two of seven fixtures since the start of the season.
McInnes said: "It’s a low point for us all, to be honest.
"It has been a tough start, as we mentioned, but the intention is to try and make sure we have the outcome that we all want.
"We’ve got to knuckle down and get a win now at Pittodrie on Sunday, and just try, slowly but surely, hopefully with some new signings, to get back to winning ways as quickly as possible.
"Until we do, we’re going to feel pretty miserable."
They face trips to Aberdeen and Falkirk in the space of four days as pressure mounts following a terrible start.

Minsu Kim became the club’s 12th signing of the summer on Thursday, joining from Girona for £8.5m, while a deal has been agreed for Portland Timbers forward Kevin Kelsy to become the 13th arrival in a move worth around £9m.
McInnes said: "We’re bringing them in to help the team and help others here.
"So hopefully, by bringing much-needed quality, it helps everybody.
"There’s no two ways about it, fans need to see more quality.
"I’m looking for a bit more quality, and hopefully, with that quality, it brings others on as well."
Findlay Curtis and James Penrice both missed penalties and were visibly distraught after the match.
McInnes stressed that responsibility does not rest with either individual, but with the collective group who allowed the tie to be decided by the "throw of a dice" that is a shoot-out.
McInnes said: "But I’ve tried, hopefully, to convey that it’s not on them now.
"Once it goes to penalties, we don’t have the advantage of the finances we’ve got as a club.
"We don’t have the advantage of playing for 50,000 fans. It goes out the window. We had enough time to show that advantage in the match.
"They are two boys [Penrice and Curtis] who are going to have good careers, and hopefully good careers at Rangers."
It remains to be seen to what extent the absence of European football affects transfer plans, although a slimmer squad will undoubtedly be required with only domestic football to navigate.
