Willie Miller: Failure to beat Old Firm this season puts more focus on Scottish Cup to give Aberdeen a lift

Celtic's Moussa Dembele scores to make it 1-0.

Aberdeen’s failure to take anything from six games against Celtic and Rangers this season is a concern.

It has been a struggle for the Reds against the Glasgow two.

Although they comfortably dealt with teams in the bottom half of the table, the real measure is how they fare against the top teams.

And it is disappointing that they have lost three times to both Celtic and Rangers this campaign.

If they could have turned two or three of those results into positive territory then you have a title challenge.

However, it was not to be.

Aberdeen have got to somehow find the measure of Celtic and Rangers.

Their 10th straight loss to Celtic is frustrating as the Parkhead side were there for the taking.

The league leaders had key players out and had taken only one point from the last two games against Kilmarnock and St Johnstone.

They had also exited the Europa League after a 3-0 loss to Zenit St Petersburg in Russia with less than 72 hours to recover.

I have played in European games and the travelling does take it out of you.

Especially the more skilful players tend to struggle after a round trip to a European game.

Those factors combined offered Aberdeen a great opportunity to secure three points but they didn’t – after a disappointing performance.

Celtic were pretty much in control in the first half and along with the goal created four decent opportunities.

Aberdeen seemed to be reliant on hitting them on the break in what looked a defensive set-up.

After the break it was better and the Reds played with a higher line to push forward.

The Hoops’ back three and keeper looked very nervous throughout the match.

Celtic looked lethargic in the second half but Aberdeen couldn’t capitalise.

The Dons now face a real battle for second as they are three points behind Rangers. Even third is not guaranteed with the way Hibs are playing.

And that puts more focus on the Scottish Cup to give the club a lift.

Aberdeen host Kilmarnock in the quarter-final on Saturday and it is important to have a cup run this season after the way results have gone against Celtic and Rangers.
