That's all from us after a weekend when Celtic have stretched their lead at the top of the Premiership to four points - and with quite a statement win.

Only a few months ago, third-top Hearts came to Celtic Park one result away from their first title in 60 years. They lost that one in the final moments, but today they were given a harsh lesson that calls into question their title credentials.

Now Celtic and Hearts turn their attention to European action on Thursday, with Celtic hosting Celta Vigo and Hearts away to Mo Salah's Trabzonspor.

Join us then. Meantime, have a read at Kheredine Idessane's match report from Celtic Park.

And remember you can watch those eight goals from today's game on Sportscene on the BBC Scotland channel at 19:15, repeated at 23:40 on BBC One Scotland and also on iPlayer.

Before Sportsound went off air, the BBC pundits were left dumbfounded that Wouter Vrancken gave no hint that he viewed the defeat as anything to do with his tactics or style of play.

They suggested the Belgian appeared to take "no responsibility" for such an embarrassing loss.

Asked twice by reporter Kheredine Idessane if he would change anything if he was to play the match again, Vrancken simply stressed the need to play and defend better - and avoid individual errors.

Give us your thoughts about that - and Celtic's clinical finishing by pressing the yellow button on this page.

Hearts head coach Wouter Vrancken tells BBC Sportsound: "Really disappointing and also the way it happened.

"We made a few individual mistakes. Two set-plays killed our game at the start of the game.

"All of their goals even, when I go back, individual mistakes and then it's difficult to win a game.

"In the set-play moments, you have to be on top of your toes, you have to be on front foot to attack the ball there. Against individual mistakes, you can't do too much actually.

"Only thing that cannot happen is that everybody starts doubting now in his own qualities. Also, when you are one of the guys that made a mistake, just learn from it.

"After tomorrow, it has to be gone because there's another game to come.

"We have to step up again and push and keep pushing."

That is the closest I've seen to Ange Postecoglou's Celtic.

That first half was devastating.

A little bit more from Celtic manager Martin O'Neill, specifically about Thursday's Europa League meeting with Celta Vigo in Glasgow.

"We'll make a couple of adjustments on Thursday evening, but we still want to try and win," O'Neill says.

"Other players coming on and getting little bits of games here and there as well helps immensely, helps the whole squad and I think it helps the confidence of the team.

"It'll be a tough game for us [against Celta Vigo]. They're very, very decent. It's a game we probably have to win. We'll go all out to try and do it."

Incidentally, Celta Vigo beat La Liga visitors Alaves 2-1 this afternoon.

Martin O'Neill does not view his side's victory as an indication that Hearts are out of the title race.

"Hearts will be still strong," Celtic's manager insists. "They've got some really good players out there playing.

"They'll still be a big challenge for us and Rangers, obviously.

"Four points at this stage of the season is absolutely nothing."

Martin O'Neill is delighted with the two goals from Callum Osmand in the young forward's first Celtic start.

"He was really, really good, played very strongly," the manager tells BBC Scotland. "That's not really his position at the end of it all, although he adapted brilliantly. He's a goalscorer.

"He was feeling his hamstring, I'm not surprised, he was feeling his at half-time. He's played very, very little football. I thought he did great."

Celtic manager Martin O'Neill tells BBC Sportsound: "I thought we played really well, really well in the game.

"Once we got a goal, players got a lot of confidence from that and we carried it on throughout the 90 minutes, so it was a really good performance from us.

"It was nice to win, it was nice to win in the manner in which we did as well - scored some really great goals. We looked really good going forward. Defensively, I thought the back four did exceptionally well.

"When Hearts got back to 4-1, I thought that was a needless thing to do. Then we get the fifth goal, which is great."

I still think Hearts are a very good side. I still think they'll finish in the top three.

But my worry with the likes of Wouter Vrancken is, if he was given the opportunity to play this game again, would he change anything?

And I don't think he's the type of person that would.

Celtic midfielder Benjamin Nygren tells Sky Sports: "It was so fun to play today.

"We haven't scored that many goals since I came here - it was extra fun to do it at home. The atmosphere here today was amazing.

"We played a good opponent a few days ago. We know we have a lot of quality players and that we're a good team.

"It's always very nice to score early. Normally, you don't keep on scoring that many goals, especially in the first half, but today we did."

One crumb of comfort for Hearts is that Celtic did not quite deliver a thumping as great as their Scottish Cup victory on 1 December 2013.

Kris Commons scored a hat-trick as Celtic cruised to a 7-0 victory at Tynecastle that took the Glasgow side into the last 16 of the competition.

Celtic defender Kieran Tierney tells Sky Sports: "We took our chances.

"Last week, I think we could have scored three or four more.

"We work on set-pieces a lot. I think it's so important these days and we got a few goals from it today.

"After a European game it's tough. It can sometimes be slow to start, but we started quick and I think the fans helped.

"There's always going to be questions. We just need to block out what people are saying."

Celtic forward Callum Osmand tells Sky Sports: "That was amazing. My first ever start, it was a long time coming, but it felt amazing out there.

"The team was amazing today. I can't fault anything. We were really clinical.

"I was a little bit tired [at half time]. I haven't played [a full game] in a long time.

"I'm pretty happy with where I'm at. Hopefully, moving forward, I can play a bit longer.

"It's about managing it, building yourself up as long as you get on those match minutes in."

Celtic's organisation was better. They worked harder as a unit. Their attitude was better, everybody doing that little bit of hard graft that you have to do and then ability takes over.

Young Callum Osmand and Colby Donovan, they're two young boys and they're the ones that almost set the tone.

Whatever the manager said to them at half-time went completely out their ears because they conceded again four minutes later.

It's a really poor performance from Hearts, but at the same time, you've got to give Celtic credit it was probably their best performance of the season.

Fantastic performance.

The best thing about Celtic today was the pace in the forward line and how they got after Hearts.

Camilo Duran through the middle is exciting me.Callum Osmand did more in 45 minutes out wide than Sebastian Tounekti has done, probably since he signed for the club.

Haissem Hassan has got a few issues defensively, but going forward he's a delight to watch.

Celtic dominated - and it could have been a bigger humiliation for Hearts.

Yet, strangely, the visitors had more efforts on goal.
