Thanks very much for joining BBC Scotland's League Cup coverage this evening - plenty of upsets and drama. You cannae beat it. We'll be back tomorrow with live coverage of the three remaining ties - Ayr United v Aberdeen, Celtic v Motherwell and St Johnstone v Hearts. All the best.

Dundee United manager Ray McKinnon: "Overall I am really pleased about tonight. There are huge positives. Blair Spittal did well and Tope was fantastic but Cammy Smith's composure and his movement for the goals was fantastic. There is quality through the leagues. It's just about impossible to bowl teams over nowadays. We just need to keep this going, keep the performances up."

Partick Thistle manager Alan Archibald: "It was awful. It was the opposite of the weekend. I feel sorry for our fans who paid good money to travel here and pay in to the game. Guys who we usually depend on just didn't do it for us today. We've had positive results but that has brought us back down. Nobody got pass marks tonight."

Alloa manager Jack Ross: "We restricted Inverness to few clear-cut chances. I am enormously proud of my players. I think it is 44 years since the club has been at this stage of the competition. I just wanted them to win the game. It won't be easy, whoever we get (in the last eight). Our record in the competition (has been) fantastic. Neil Parry had a great save in the first half and we were under the cosh at that point. With having the goal, we always had something to protect and we did that very well. The players are loving that feeling of coming in having won the game. It bodes well but I've been in football long enough to know it can change very quickly."

"Quitongo, I thought he was absolutely superb. He ran that back four ragged. I think Jim Duffy's side are going to be a force this season. A thoroughly deserved victory for them tonight."

Dundee United's hat-trick hero Cammy Smith: "We came here tonight wanting to take the game to them. They are no mugs, it's a great victory. We are down in the Championship so this year it's all about bouncing back. The cups are a bonus, we are concentrating o the league. It was a great performance by us, we looked dangerous, we have to be happy with tonight's work. Aberdeen thought my best interests were to go out on loan this season. It wasn't like I was being shoved out the door. I am enjoying playing regular football. It's a long season ahead. I want to get goals this season."

League One Alloa deserve a special mention, registering their sixth consecutive win and maintaining their 100% record this season. And against a good Caley Thistle side, too. They'll be rubbing their hands at the thought of who they might get in tomorrow night's draw for the quarter-finals.

It's been a good night for three lower-league teams, with Alloa, Dundee United and Morton all enjoying wins against Premiership opposition.

 "I think it was Hamilton's mindset, that they just had to turn up. Morton came out the traps and were at it right from the off."

Morton have just a minute to see out away to Hamilton to book their place in the last eight of the League Cup.

Jeez-oh, I think I'd better dig out some photos of the Doonhamers celebrating. Those joyous Hibs ones from a few minutes ago seem really out of place.

"Hibs are comatose at the back! Queens have monstered them!"
