If Aberdeen are to lift the Scottish Cup for the first time since 1990 they will have to do something that has been pretty rare in recent years.
The Dons secured a semi-final spot courtesy of Tuesday’s 2-0 victory over Rangers at Ibrox.
In the last four, the Reds will face Celtic at Hampden on April 14.
Success at the national stadium would send the Dons into the final against either Hearts or Inverness Caley Thistle and would also mean they had beaten both Celtic and Rangers in the same season for the first time since 2007-08.
Darren Mackie played a big role in victories over the Glasgow giants 11 years ago.
The former Pittodrie striker scored the only goal at Parkhead in March 2008 as Jimmy Calderwood’s side beat the Hoops in the quarter-final of the Scottish Cup.
Two months later Aberdeen beat the Gers 2-0 at Pittodrie on the final day of the league season with Mackie and Lee Miller on target.
Mackie, 37, reckons Derek McInnes’ Dons have what it takes to do the Glasgow double again this season and reach the final.
He said: “They are definitely capable of beating Celtic.
“Aberdeen are going into every game expecting to win whether it’s Celtic or Rangers or somebody else.
“That can only be a good thing – especially when you play Celtic and Rangers – to have the belief they can get a result.
“In previous games Aberdeen have held their own against Celtic.
“Last weekend they drew 0-0 and in the League Cup final Aberdeen were unlucky to lose (1-0).
“The Dons will be on a high and the pressure will be on Celtic and Aberdeen will have the belief and confidence to get through. The fans are enjoying it and hopefully they will have more to enjoy at the end of the season.”
Aberdeen’s win in Govan on Tuesday was their third triumph against Rangers in Glasgow this season.
The Dons had previously won 1-0 at Ibrox in the Premiership in December and at Hampden in October’s League Cup semi-final.
Mackie, who made 364 appearances and scored 69 goals for the Reds, is delighted to see the Dons besting their Glasgow rivals in their own backyard on a regular basis.
Mackie, who also played for Phoenix, Turriff United and Inverurie Locos after leaving Aberdeen in 2012, added: “Under Derek McInnes Aberdeen have won regularly in Glasgow in recent seasons.
“It’s been amazing that they have been able to do that. In my time I can’t put my finger on why we found it tougher. We did win a couple of times against Celtic at Parkhead.
“At Ibrox we just couldn’t quite get over the line. I can remember games where we went in front and games were tight but we just couldn’t quite manage to win.
“The current squad have great belief that they can get a result wherever they go and they keep showing that with the results they’re getting.
“Aberdeen fans are going to games in Glasgow full of hope and expectation and people are expecting them to do well.
“It’s great that Derek McInnes has got the belief in the players’ heads that they can get results anywhere. They play with no fear and as a former player and supporter of the club it’s good to see.
“I think people thought they might struggle more this season, but they haven’t.
“OK, they are not sitting second, but they have reached a cup final and are in the semi-finals of the Scottish Cup.
“It’s been another good season and Aberdeen will be looking to finish with a trophy. If they have a strong finish to the season hopefully they can chase down Rangers and finish second.
“It will be tough to reach the Scottish Cup final but the manager will have them fully prepared.”
Mackie was thrilled to see the Dons win at Ibrox this week and prove some of the doubters wrong.
He said: “Aberdeen have a lot of good players in their squad and deservedly won the tie.
“At times they had to do a bit of defending but it’s goals that count and Aberdeen got them.”
