CELTIC and Rangers will face one another in a semi-final for the third season in a row after they were drawn together in the last four of the Betfred League Cup.

Aberdeen’s 1-0 win over St Johnstone last night, courtesy of a 90th-minute winner from Adam Rooney, means the Pittodrie side will face Championship outfit Morton in a match which will probably be taken away from Hampden Park.

The ties will take place over the weekend of October 22 and 23, with the Old Firm game most likely to be moved to the Sunday.

Derek McInnes, the Aberdeen manager, admitted he was happy that he would be taking on Morton, the club he began his career at, but was angry this quarter-final tie had been moved to a Thursday, 48 hours after Rangers played.

He said: “We need a big effort from everyone for this one on Sunday. It’s ridiculous that Rangers have 48 hours extra of recovery before a league game when there doesn’t need to be.

“Why our game was moved to the Thursday, I don’t get. But it is what it is – and we’ll be ready from them come Sunday.”

A loud cheer came from the Aberdeen players’ lounge when the draw was made but McInnes warned against anyone believing his team were all-but in the final even if it was the semi-final he wanted..

He said: “When you have the Old Firm in the draw with a team from the Championship, we probably all want the Championship team – and Morton probably wanted us. But it’s my club, really. Some of my fondest memories in the game were there.

“I’m so pleased they’ve made the semi-finals. A lot of my friends are Morton supporters and I’m delighted to be up against them – and we know how tough it will be. You have seen before that any team in a semi-final can win.”

There was an argument in the tunnel after the match; however St Jonhstone manager Tommy Wright played down the incident.

Wright said: “Aberdeen have a right to celebrate but they left the dressing room door open and the music was deafening. Our players were a bit upset and one of them shut the door. But there was nothing in it.”

Wright felt his team were unfortunate not take the game into extra-time.

He said: “I’m obviously disappointed. When you get into the last minute of normal time, we thought we’d done enough to take it to extra time.

“We just couldn’t get that goal. There was nothing in the game. Both teams cancelled each other out. Aberdeen had better possession, which you’d expect from the home team and with the quality players they’ve got. It looked like one goal would decide it and unfortunately we didn’t get it.”
