That's all from us tonight, folks.

Cheers for joining again. You'll get more reaction on the site.

Cheerio.

You should know this by now, but our coverage of every Scottish Premiership team is bigger and better than ever before.

Here's everything you need to know to make sure you never miss a moment.

You'll get more reaction and analysis on your club's dedicated page.

St Mirren boss Stephen Robinson tells BBC Sportsound: "It's an opportunity missed.

"First half we were brilliant and in total control of the game, and we score a fantastic goal, it should have been two.

"Then, it was as if we thought, 'let's not do that again, that was really good' and we do something completely different at the start of the second half.

"We only have ourselves to blame. If you're scoring two goals away from home, you should be winning, but if you concede four, you won't be winning any games.

"We'll restart, we've been fantastic, the boys have been brilliant, I haven't been too hard on them.

"We shot ourselves in the foot with the 15 minutes after half-time. We have to defend better."

Ross County manager Malky Mackay tells BBC Scotland: “I'm really proud to be honest with you, can’t ask for any more of my players.

“We lose a goal, it’s a fantastic strike from Graeme Shinnie, we’ve spoken to the players about losing bad goals, that was a terrific goal so I’ve got no complaints.

“Again, I thought we started well and were getting into good areas, the sending off kills us clearly.

"You look at that and think it could be a really tough night, but we turn it into a hell of a cup tie.

“With five or 10 minutes to go, Aberdeen are piling players on to go and sit further and further back and I can be nothing other than proud of my players.

“If we keep playing like that we’re going pick up points in the league.”

Hibernian boss Nick Montgomery tells BBC Sportsound: "I thought it was a really good game of football, entertaining. First half I thought we were the better team, we created a lot of half chances, just lacking that composure in the final third, but they're good on the counter attack.

"We could have dealt with it better, but from that moment on, we controlled and dominated the game. They had two shots on target and both went in, so that's a good accuracy to have, but all in all, we more than deserved to win the game.

"St Mirren have had a great start to the season, but we made them tire and that's when we started to expose them. We switched the ball really well and made them do a lot of running. With the ball, we were better, it was an exciting cup tie."

On his half-time team talk: "I told them to stay calm, keep playing and don't get sucked into thinking we need to change the game-plan. We have the belief now."

On drawing Aberdeen: "It doesn't matter who we play, it's a semi-final. It's a knockout and now we are one game away from a final, but in reality, it's not even in my mind at the moment. Full focus is Dundee at the weekend."

Rangers manager Michael Beale tells BBC Sportsound: "Today's win was much convincing than the weekend.

"It was an excellent first goal [from Abdallah Sima]. It was a heck of a finish. It was an excellent goal from Ridvan [Yilmaz]. It was a big moment for him personally. Hopefully, this is the start of him showing us what he really can do. He came off with a tad bit of cramp.

"We may have lost Kemar [Roofe] tonight. He felt his groin in the first half. Let's hope it's nothing serious, let's hope we've caught it at the right time.

"We'll look forward to that [semi-final with Hearts] when it comes around."

Michael Beale has just confirmed that Kemar Roofe's withdrawal was as a result of a groin injury.

The striker just can't catch a break when it comes to fitness.

Another big injury blow on a positive night for Rangers.

The evidence of the last few days would suggest there is a growing body of evidence to argue that Aberdeen have turned a corner.

Having given Eintracht Frankfurt a scare in Germany, Barry Robson's side have followed that up by taking care of their Ross County double-header.

It isn't just about the results, but the consistency of performance has very visibly improved over the last week.

A number of the new recruits - particularly Richard Jensen and Stefan Gartenmann at the back - look to have now settled in and Aberdeen are now starting to reap the rewards.

This will continue to be a work in progress as Robson's men continue to juggle domestic and continental commitments, but there are now real signs this new-look side are starting to grow in confidence.

As for County, it has been a tough double-header this week. Malky Mackay must now ensure that the back-to-back defeats don't derail what has been a pretty positive start to the season.

And he doesn't have much time to lift the spirits, with Hearts heading north on Saturday.

Rangers sought a better level of performance after labouring to their win over Motherwell at the weekend.

They got that from minute one with the passing far slicker, the movement far better and at one stage it looked like a mere formality and case of how many.

Livingston just could not get out or retain possession for any length of time. However, a slight dip in level for a short spell, afforded the visitors some hope and they came very close to levelling.

That hope was quickly extinguished by Ridvan Yilmaz and Rangers put the seal on it with a third and fourth late on. That will bring confidence.

Four goals and now four wins and four clean sheets in a row. There has been criticism along the way but the performance was encouraging and the outcome deserved.

David Martindale will be frustrated at the opening, encouraged by the moments that brought a glimmer of hope, but ultimately will feel a sense of deja vu having seen a similar outcome on their last visit to Ibrox.

It felt like a long shot given they have never won at Ibrox and ultimately that proved to be the case.

Livingston boss David Martindale tells BBC Scotland: "I think the first goal is a foul. It's not a huge push but there is a push.

"For the life of me, I don't know how we've not got a foul there. Ibrox away, a quarter-final... I've not seen many of them given. If that was our goal? I'm not so sure.

"I felt we started the second half really well. After the second goal, we've got a mountain to climb."

• Hearts v Rangers
• Hibernian v Aberdeen

Both ties will take place at Hampden on the weekend of 4/5 November, with the final set for 17 December.

Aberdeen manager Barry Robson tells BBC Scotland: "The sending off changed the game a bit, it took us a while to get into rhythm, but we were in total control.

"The aim was to get to Hampden. Let's see how we can perform and how far we can keep progressing.

"We've had to go to really tough places and we're still fighting on three fronts."

Rangers captain James Tavernier tells Viaplay: "We started strong, it was important we did that. We moved the ball well, really quick.

"At the weekend we turned the ball over too many times. The gaps eventually opened up for us tonight."

"[The League Cup] is the first cup you can get your hands on in the season. It's something we really want to get and we've put ourselves in a great position."

There you go then, both Edinburgh sides separated.

Here comes the draw...

Rangers were worthy winners. 4-0 was probably about right.

Four games for Rangers, four wins, eight goals scored, zero conceded. You wouldn't think it though, would you?

Nevertheless, it's another Hampden appearance booked for Michael Beale, who is slowly easing a mountain pressure on his shoulders.
