Dons striker Sam Cosgrove insists they have to channel their Betfred Cup heartache into getting a win at Ibrox.
Aberdeen were edged out 1-0 by Celtic at Hampden on Sunday in the Betfred Cup final.
However, the Reds have to quickly get over that pain because they face Premiership leaders Rangers in Govan tomorrow evening.
Cosgrove, who was drafted in to start Sunday’s showpiece, was hugely disappointed by the narrow loss at the national stadium.
But the 22-year-old insists Aberdeen can be proud of how close they pushed Celtic and now he wants to use the frustration of cup final defeat to secure three points at Ibrox.
Cosgrove said: “We’re disappointed obviously, but I think as a team, a squad and a club we can hold our heads up high.
“The performance we put in wasn’t pretty but it was effective for the majority of the game.
“We were just lacking that clinical edge really and I feel we have to be proud as a club.
“The fans were fantastic as they always are – it was always a given that they were going to be there in their numbers and in the end we’re disappointed we couldn’t give them that victory.
“It is about channelling this disappointment.
“We’re an absolutely fantastic group and we have a right to be disappointed.
“But we have a massive game coming up tomorrow and that could be a blessing in disguise.
“It’s gets us back up on our feet and looking to get a good result against Rangers. It won’t be difficult to lift ourselves.
“We’re disappointed but we are a great group and we will get back on the ball.
“We weren’t far away from beating Celtic on Sunday, so if we can do that against them we should be able to do it against Rangers as well.”
Cosgrove believes the Dons can learn from their mistakes at Hampden.
The former Carlisle player believes it was just a clinical edge that was lacking, at both ends.
Celtic’s winner came from former Reds loanee in the fifth minute of first half stoppage time following a six minute delay while Gary Mackay-Steven was treated following a collision with Dedryck Boyata.
Cosgrove wants Aberdeen to learn from the narrow loss, but believes they can take some confidence from the performance.
He added: “You have to learn from these mistakes. It’s just being clinical because I think we’ve kept them quiet for most of the game. Joe Lewis has had something like two saves and one of them is a save before the goal.
“We’ve done our job all over the pitch, but it’s just getting that clinical edge, keeping a clean sheet and scoring a goal.
“They are the obvious points we need to work on.
“It wasn’t the perfect performance, but it was up there.
“I think that performance would get us a win in 90% of games that we play this season. If we can keep those standards it will be good coming into a busy time.
“We’re disappointed but I think we can take confidence from that going into a busy period.”
Some believe the delay, while medical staff tended to Mackay-Steven, had an impact on Aberdeen’s concentration prior to Christie scoring, but Cosgrove doesn’t think that was the case.
“I don’t think it affected us. It’s never nice to see one of your team-mates and one of your friends go down seriously hurt,” he said. “But we are professionals and we still had a job to do.”
Derek McInnes drafted Cosgrove in for his first start since the 2-1 loss to Hearts at Tynecastle on October 20.
Cosgrove says he always felt it was a matter of time before he would return to the team and believes he can make important contribution in the weeks ahead with the Reds tackling a further eight games in December.
He said: “I’m always ready to come into the team when I’m chosen. I knew it was only a matter of time before I would get my chance again.
“I just want to do my best for the team and the club and that’s all that was on my mind and I’ll do as much as I can.”
