- Old Firm derby at Ibrox to be played on Hogmanay
Tune into Sportsound on 810MW at 18:30 for a look back at Celtic's defeat to Barcelona and all the day's sports headlines.
Presented by David Currie, with guests Pat Bonner and Richard Wilson.
Miles Addison, Kilmarnock: "As last night showed the standard [between Scottish football and Europe] is way off. In saying that, we go to Celtic Park in a couple of weeks and some of the boys are saying the scoreline could be similar when we play them. We're slightly worried because I'm sure they will still be angry from the result."
Brian Easton, St Johnstone: "It's the best team in our country getting turned over like that, it's not great for Scottish football or for Celtic. But we've played Celtic this season and, already compared to last season, I've seen big differences in their team and they've looked like they're improving."
Jack Hamilton, Hearts: "I think it was great to watch a fantastic Barca team with Messi, Suarez & Neymar up front and see how good they actually were. It's a learning curve as well for Celtic."
Alan Stewart: As a non-Celtic fan I feel they shouldn't be embarrassed by last night. No team on the planet could have defended against Barca. It was total football and a joy to watch.
Ian Ross: No team would have done any better last night. Barcelona were on another planet.
Gordon Christie: Even if they had played at their best score would have been the same.
Mark Warburton has urged his Rangers squad to re-focus following their Old Firm derby defeat.
Rangers will seek to move on from the 5-1 loss at Celtic Park - starting with the Premiership encounter at home to Ross County.
"We weren’t Rangers against Celtic in terms of being on the front foot and being positive, so that’s what we have to show at Ibrox on Saturday," Warburton told Rangers TV.
"Ross County are a very strong team who had an excellent season last year. Jim [McIntyre] has done a great job there and they are a team who are just behind us in the table.
"If we do what we do well, the result always follows."
Until Tuesday night at Camp Nou, Kieran Tierney had earned nothing but plaudits after his rapid progress, first into the Celtic first-team and then the Scotland set-up.
But the teenage left-back admits it was yet another giant leap to face Lionel Messi, Luis Suarez and the rest of the Barcelona side.
"He just drifts in and out," Tierney said of the task of marking Messi on a night the Argentine scored another hat-trick in Barcelona's 7-0 Champions League win.
"But you're not just containing Messi when he moves in, you've got Suarez or the full-back.
"It's hard. You need to be concentrated at all times. One second and you're man's away.
"It was 90 minutes but felt much longer than that.
"Obviously I played in the six qualifiers, but none of the teams were Barcelona.
"As a 19-year-old, it's obviously hard going into games like this, but it's hard for everybody. There's a lot to learn."
Celtic goalkeeper Dorus de Vries admits that Tuesday's 7-0 Champions League thumping by Barcelona was his worst moment in football.
"It wasn't nice facing them, especially as a goalkeeper," said the 35-year-old Dutchman. "They are so powerful, such an attacking force.
"You always look at your own performance and think what's possible, but I felt pretty helpless at times and, as a goallie, that's just sometimes how it is.
"Conceding those goals against arguably one of the best footballing teams in the past decade with arguably the best players in the world taught us a lesson.
"There's always things to review, but once Barcelona start ticking you can see the amount of beautiful goals they score, the amount of power and pace they put into it.
"But we should do better as a team and we are going to learn from that and make sure it will never happen again."
Owen Coyle has accepted the responsibility for Blackburn Rovers' disappointing start to the season.
The 50-year-old Scot's side were beaten 2-1 away to Leeds United on Tuesday and remain bottom of the English Championship with only two points from their opening seven games.
"When all is said and done, I've got the ultimate responsibility to go and win games and points," the manager told BBC Radio Lancashire.
"We've not not done that well enough at this point and that is something we need to address quickly."

Scottish League Two player of the month Josh Peters says he took a step down - and a step up - when joining Forfar Athletic after being released by Hibernian in the summer.
The 19-year-old striker, who has scored eight goals in 11 games, spent only four months at Easter Road after signing for the Edinburgh outfit from the Highland League's Strathspey United amid interest from a number of other clubs.
"It's a bit of step down from full-time football at Hibs," said Peters, who was in their development squad. "But the quality of the football is a step up going into first-team football.
"It's the first time I've played senior and I'm really enjoying it at the moment.
"It was a big step up from Strathspey to Hibs. It was three or four steps up actually, but it was an offer I couldn't turn down.
"I did well and came close to getting a first-team contract, but with the quality and standard of the attackers at Hibs, it would have been difficult for me to get a game if I had signed a contract.
"I'm aiming to prove people wrong."
Jordan Kirkpatrick has thanked Jack Ross for helping him to the Scottish League One player of the month award and tipped the Alloa Athletic manager for bigger things.
The 24-year-old winger has scored eight goals since joined the Wasps after leaving Dumbarton in the summer and his scoring exploits in turn helped Ross win the manager of the month award.
“The gaffer has helped a lot - not just with me - in terms of confidence and expressing ourselves," said Kirkpatrick. "He’s helped me enjoy playing again.
“He is very good one-to-one with you and knows a lot about the game. From what I witnessed at Dumbarton, he helped a lot of the boys there.
"He’s came here and we all saw a turn-around from Alloa last year - even though they were at the stage where they were facing relegation, they still managed to become a bit more stable and consistent.
"It just shows you that he can definitely go very far in the game if he just keeps doing what he’s doing."
“I had a really good time with him there and it seemed like the obvious choice to sign with him again."
Motherwell appear poised to sign former Swansea City midfielder Lee Lucas for the second time this season.
The 24-year-old had signed a short-term deal with Well shortly after being released following 15 years with the Welsh club in the summer,
However, Lucas was subsequently also released by Well on transfer deadline day on 31 August after picking up a hamstring injury during his one appearance in a 3-1 League Cup win over Annan Athletic.
The Welshman had only made four previous senior appearances in a career riddled with injury - his Swansea debut as a substitute in 2011 and others on loan to Burton Albion and Cheltenham.
Former Scotland defender Stephen McManus believes Hearts' teenage centre-back John Souttar has the potential to play for his country, but should not be rushed into the squad.
"He's going to be a tremendous asset for the country," said McManus.
"He's not played in a lot of high-profile games, [but] he's developing very well. It's important with guys like that, that you don't pin all your hopes on them, because it puts pressure on their shoulders when they're so young.
"You need to nurture them."
League Two manager of the month Gary Bollan says his August award with Forfar Athletic is "recognition for the whole club" and has praised an improved mindset in the dressing room.
“It’s a combined effort," he told sponsor Ladbrokes. "Last year, for a good bit of the season there was a negative mindset, and now the players we’ve brought in have changed all that and there’s a much more positive outlook on things at the moment."Copyright: SNS
