Aberdeen must overcome their Glasgow hoodoo to remain Celtic’s main challengers and land silverware.
The Reds are now in a real battle to finish Premiership runners-up for a fourth successive season.
Leapfrogged in second spot by Rangers after the 2-0 defeat the Dons have now lost all three games to the Ibrox club this season.
The inability to take anything from the Glasgow two this term has been Aberdeen’s Achilles heel.
Derek McInnes’ side have also lost both games to Celtic this season. That’s 15 points dropped to the Old Firm.
If they had won a couple of those games they would be sitting pretty in second and putting pressure on the Hoops.
Aberdeen’s record against the other teams in the Premiership is superb – they just haven’t produced it against Rangers or Celtic when it matters.
It is an affliction that has affected successive Aberdeen teams.
One win at Ibrox in 27 years and no league win at Parkhead since 2004. That has to change if Aberdeen are to remain Scotland’s second force.
This was the first time Derek McInnes had faced Rangers since turning down the Ibrox managerial job in December. It was a subplot that added extra spice to an event that already had enough fire and fury.
Speculation linking McInnes to the Gers job had raged on during the two earlier defeats.
The party line within Pittodrie was that the speculation on the manager’s future did not negatively affect those Dons performances.
Results before the speculation and after McInnes rejected Rangers, days after they made an official approach to talk to him, suggest otherwise.
