Boss Derek McInnes today backed injury-ravaged Aberdeen to get the wins required to secure European qualification.
The Reds crashed 2-0 at Rangers to confirm the Ibrox club will finish Premiership runners-up.
It is the first time since 2015 the Dons will not be second in the league to champions Celtic.
Without five key players for the clash the Reds’ injury crisis also increased with fears Connor McLennan could be out for the season with a hamstring tear.
McLennan’s injury was an early blow as Aberdeen lost to two converted penalties.
And McInnes insisted referee Don Robertson was “kidded” by Nikola Katic into awarding a second penalty and sending off Andy Considine.
McInnes said: “There are three games left and we know we have a couple of wins in us.
“We move on now.
“We will see who is fit and available and will go and have a go again on Saturday (against Celtic at Pittodrie).
“We need a big last effort from everyone at the club to get our European spot.
“Sunday at Ibrox wasn’t going to decide anything about European spots.
“We would have needed a lot of things to go our way to get a positive result at Ibrox.”
McInnes was left frustrated that little went his team’s way in Govan as Rangers netted both goals from the penalty spot.
Winger McLennan was also taken off injured after only 14 minutes with a hamstring tear.
Aberdeen face a sweat to see if he can recover before the end of the season.
McInnes said: “We went to Ibrox without six starters as we are really up against it with injuries.
“We tried to put a team together to come out and try to still be competitive against a good Rangers side. I am disappointed.”
The loss of McLennan, the only natural winger available for the Dons, was the first blow and McInnes was frustrated at both penalty decisions.
He said: “Both penalties were very harsh on us.
“With the first one I can understand why the referee has given it but Lewis (Ferguson) should maybe go down as (Jermain) Defoe has fouled him in the build-up to it.
“Lewis when he feels the contact should maybe go down and has been too honest.
“He was then knocked a bit off balance and has put his foot on to the Rangers player’s foot.
“The Rangers player has made sure he got the penalty and went down.
“We had to overcome that blow but we are still in the game at 1-0, as difficult as it is.
“The second penalty kick, words fail me how that can be given. It is a terrible decision and had a huge impact on the end result.
“The second goal effectively kills the game as we were also down to 10 men.
“The reaction from the Rangers player was bad enough but for the referee to have been kidded by that to give the penalty is really disappointing.”
Asked if he had a chat with the referee, McInnes said: “I did. But that is between us.
“I was disappointed he has not seen that (second yellow for Considine) for what it was.”
Considine, who signed a two-year contract extension until 2021 in the build-up to the Ibrox clash, will be suspended for Saturday’s home clash with Celtic who only need a point against Aberdeen to win the Premiership crown.
The Dons cannot appeal the second yellow to Considine.
Aberdeen travelled to Ibrox with five first-team players out injured – Niall McGinn, Graeme Shinnie, Gary Mackay-Steven, Shay Logan and Tommie Hoban.
On-loan Greg Stewart was also carrying a sciatic nerve problem but came off the bench in the second half.
Winger McLennan is now added to that injury list. On McLennan, who limped off early on, McInnes said: “It looks like a tear.
“Grade one will be a couple of weeks at best.
“Anything more than that and it will be the end of the season for him.”
