Brendan Rodgers was transported back to his first spell in charge of Celtic as his side struck six first-half goals against Dundee.

Celtic have lost top spot in the cinch Premiership since the winter break, drawing twice and winning narrowly in their other three league games.

But they rediscovered their groove with their biggest victory of the season as they thrashed Tony Docherty’s side 7-1 at Celtic Park.

There were seven different scorers for Rodgers’ side as Cameron Carter-Vickers, Adam Idah, Matt O’Riley, Daizen Maeda, Greg Taylor and Callum McGregor struck before half-time substitute Daniel Kelly curled home his first goal for the club.

Rodgers said: “It was a top performance. We had players coming back, connecting the game, speed in the game, creativity and a real ruthless mentality.

“I have said about the pitch a few times but a big congratulations to the staff who have been working hard over the past few weeks to get it to a level that allows us to play at that speed. And you can see the difference it makes.

“So I thought all round, from the stands to the pitch, it was a great night for us.”

Rodgers, whose side remain two points behind Rangers, added: “It felt more like when I was here the first time – that ruthless mentality of the team, simplicity of the game and the football we played. And that’s why we are here, to entertain the supporters.”

Rodgers had called for positivity in the stands before the game and the noise at the half-time whistle was more akin to a Champions League night, helped by the fact that Kilmarnock were beating Rangers before a second-half fightback from the leaders.

Rodgers said: “There was a really nice moment at half-time when they were coming in. The fans could see then how the level of performance had jumped up. We had everything we wanted from the game – the runs, the movement, the ambition.”

Dundee’s second-half performance offered some comfort for Docherty, whose side got a consolation through substitute Michael Mellon despite having Finlay Robertson sent off.

But Docherty was still reeling from their first-half collapse during the post-match media conference.

“It’s something I have not seen in the group so I am actually a bit shocked to see the level of goal we have conceded,” he said.

“We need to take ownership and responsibility for that, for not defending crosses, not defending our box properly, getting done by cutbacks, getting done on the insides.

“I have to say I thought Celtic were outstanding but we can do more and we need to take responsibility for that.

“But I have to defend those players, they have been brilliant for me this season and there has to be a wee bit of reality in terms of us being a newly-promoted team. I am not taking away the accountability from myself and the players and I would like to apologise to the support.

“But I will always back that group of players because I don’t think we have been lower than seventh in the league.”

Celtic hit form with a 7-1 victory over Dundee following a first-half goal spree at Parkhead.

Cameron Carter-Vickers started the rout in the seventh minute and goals from Adam Idah, Matt O’Riley and Daizen Maeda had Celtic four up before the half-hour mark.

Greg Taylor and Callum McGregor made it six before the break and Daniel Kelly marked his league debut with a brilliantly-taken goal.

Dundee were down to 10 men through Finlay Robertson’s red card when they pulled a goal back from Michael Mellon, although the atmosphere had already lost a bit of an edge following Rangers’ comeback at Kilmarnock.

The Light Blues’ 2-1 victory keeps them two points ahead of Celtic at the top of the cinch Premiership.

However, Celtic have moved back to one behind on goal difference and secured a morale boost with their biggest win of the season after struggling to find their groove since the winter break. They had drawn twice in their previous four league matches and needed stoppage-time winners in the other two.

Manager Brendan Rodgers had called for positivity from the stands on the eve of the game after referencing the dissent that greeted one of his substitutions during the champions’ late win at Motherwell on Sunday.

His players ensured there was no opportunity for any negativity to emerge, although Dundee twice came close in the first two minutes through Curtis Main and Owen Beck.

Beck had kept Maeda quiet at Dens Park on Boxing Day but Yang Hyun-jun got an early edge when he got past him and drew a foul which earned the on-loan Liverpool left-back a booking.

There was further punishment from O’Riley’s free-kick as Carter-Vickers rose above Amadou Bakoyoko to head home his first goal of an injury-disrupted season.

Beck was fortunate not to receive another booking from referee Matthew MacDermid for a reckless tackle on Yang and Celtic continued to put the visitors under pressure as O’Riley was twice denied.

The home support were given another boost when news emerged of Kilmarnock’s opener and Idah had them celebrating in the 18th minute with a brilliant header from Alistair Johnston’s cross to net his fifth goal since joining four weeks ago.

O’Riley ran on to Taylor’s perfect cross to head home four minutes later and the midfielder turned provider as his pass found Maeda’s run across the box. The Japan international had plenty to do but a brilliant touch fooled Joe Shaughnessy and he curled into the far corner.

O’Riley sent a brilliant volley off the bar from 22 yards and Taylor’s run into the box was rewarded when Johnston’s cross ultimately fell for him as the left-back stroked home from eight yards in the 36th minute.

Main had a goal disallowed for offside following a VAR check before McGregor drilled home in stoppage time after an exchange of passes with Taylor with Yang once again involved.

Celtic went off at half-time amid noise akin to a Champions League night but the atmosphere dampened down as news of two quickfire goals from Rangers filtered through early in the second half.

Dundee manager Tony Docherty had made three half-time changes and his side looked more compact but half-time substitute Kelly showed composure beyond his 18 years to curl into the top corner after Yang’s low cross came to him on the edge of the box.

The Celtic Park DJ dug out the Magnificent Seven theme tune that used to follow Henrik Larsson’s many Parkhead goals and more fanfares looked on the cards.

Luis Palma curled off the Dundee bar and Robertson received a second yellow card for a late challenge on Johnston in the 76th minute.

However, it was Dundee who added to the scoring eight minutes later when Mellon volleyed home a cross from fellow substitute Aaron Donnelly.

Brendan Rodgers vowed Celtic would not be selling any key players this month after rejecting Atletico Madrid’s bid for Matt O’Riley.

Rodgers described the LaLiga side’s offer for the Denmark midfielder as way below Celtic’s valuation but claimed the money was irrelevant with the club not needing to sell.

Celtic’s lead at the top of the cinch Premiership was cut to five points by Rangers’ win over Hibernian on Wednesday with the Ibrox club still holding one game in hand.

And Rodgers is keen to emerge from the window with a stronger squad rather than a weakened one.

“Matt is a player we don’t want to lose and he won’t be going anywhere in January,” Rodgers said.

“It’s a great testament to him and what the club can do for a player. He won his first international cap this season and Atletico Madrid are a big club in European football.

“But he is very much part of what we are doing. He has been a joy to work with and I had a good chat with Matt and he is someone who will be here for us in the second part of the season.”

The 23-year-old is pushing for Denmark’s Euro 2024 squad and appears happy to continue developing at Celtic Park. The former MK Dons player has produced 10 goals and 12 assists this season and recently extended his contract until 2027.

“It’s one of the things I have been really impressed with Matt, his mentality, his professionalism and the respect he has for Celtic,” Rodgers said.

“He had an opportunity in the summer but he was very happy to extend here and obviously Atletico Madrid is a huge club but he also knows he is in a great place here. He has really kicked on this season and he wants to continue with that.

“Firstly, you have a value of the player and certainly what has come in for Matt in the time I have been here is nowhere near the valuation of the quality of player he is. But even if it was we are in a position where we don’t want to sell.”

When asked if it would take a special offer to prise any of his key players away this month, Rodger said: “They won’t be going, it’s as simple as that. January is a difficult month anyway, whether it’s bringing players in or looking to sell players. It’s not something we want to do. We have no interest in that.”

Nicolas Kuhn is Celtic’s sole January signing and the former Rapid Vienna winger is in line to make his debut against Ross County on Saturday.

Rodgers revealed work was continuing to add more but nothing was imminent.

“We have a lot of quality players in our squad that are improving and developing and I want to add more to that,” said the Celtic manager, who will welcome Cameron Carter-Vickers back from injury against County.

“But it’s never easy to add quality because other clubs don’t want to lose quality players.

“But it’s something that is continually being worked on and I hope before the window shuts that we are able to do that.”

He added: “I don’t want to be in a rush to bring in a player, it always has to be the right player.

“And also I want to be here for a period of time, as long of course as I’m successful, so I want to create an opportunity for young players to come through here.

“Everyone talks about signings and I always say you might have someone within your academy, but you need to have the space for those payers to flourish and develop.

“So, yes, I hope we can add to the group, and I’m confident that we can, but also I want to develop the talents that are here and continually grow them.”

Celtic manager Brendan Rodgers is unaware of any concrete interest in Matt O’Riley and believes the midfielder is happy to continue improving in his team.

Reports claim Spanish league leaders Girona are considering making a move for the Denmark international ahead of the transfer deadline.

But the 23-year-old signed a new contract earlier in the season that ties him to Glasgow until 2027 and appears focused on his game.

Rodgers said: “I’m not aware of any (interest). But it’s natural, if you’ve got good players then of course they will attract attention. But I’m not focused on that at all.

“We don’t want to be losing any (of our best players). The plan was to add to the squad and that’s still the plan.

“If a player doesn’t want to be here then my experience is you are better off moving them on. It’s as simple as that.

“Of course the club is in a really strong position with no need to sell and no thoughts of selling.

“Matt is really, really happy here. He signed a new deal, he has really progressed, he is into double figures now in goals, and his assists are there.

“For him as a young player, he is a brilliant professional, all he wants to do is improve and he can see the improvement here. Just take it day by day and assess it from there.”

In terms of incomings, Rodgers was looking for quality rather than quantity this month and believes he has added that in former Ajax and Bayern Munich reserve winger Nicolas Kuhn.

“There’s a lot of work going on and hopefully before the window shuts, we can improve the squad,” he said.

“It normally goes right through to the end. I am quite relaxed on it. I know what we need to improve but unless it’s the right type of quality and player then we won’t be in a rush to do anything.

“And likewise if something comes in too late that doesn’t suit the squad and how strong we are then we won’t need to do anything.

“If it was just about numbers we could have had people in on January 1, but it’s not. It’s about getting quality in and that can take time.

“Nicolas has had that big-club experience before. He is a very talented player. Now he is at an age where he has done very well with Rapid Vienna and can make that next step.

“He fits the profile in terms of how we work – he is super quick, direct, dynamic and we feel we can continually improve his game.

Neither Kuhn nor Cameron Carter-Vickers, who is on his way back from a hamstring strain, will play in Sunday’s Scottish Gas Scottish Cup fourth-round tie against Buckie Thistle.

Rodgers said: “Nic won’t be involved at the weekend. He had actually been quite a period out. He had an operation on his teeth so he lost a bit of strength. But he will be okay for Ross County.

“Cam won’t be involved this weekend but by Ross County he will be fine.

“He has been out on the field for a little while. It’s been a frustrating period for him in the opening part of the season, he has picked up some niggles on the back of not having a full pre-season. But we are really hoping he can stay fit and strong for the second part.”

Celtic manager Brendan Rodgers praised his players’ mentality after they followed up their derby triumph with a dominant 3-0 win over St Mirren.

The cinch Premiership leaders maintained the eight-point advantage they opened up with Saturday’s victory over Rangers, thanks to a flying start which saw Daizen Maeda net inside 60 seconds and Matt O’Riley slot home his 10th goal of the season six minutes in.

St Mirren had Toyosi Olusanya sent off in first-half stoppage-time and had goalkeeper Zach Hemming to thank for keeping the score down after Greg Taylor volleyed home on the hour mark.

Rodgers said: “It can always be a tricky game mentally and physically after a Rangers game but I thought we dealt with it really well and we made the start we wanted to. It was good tempo, good speed, so that set us up well in the game.

“These games are so important and I think as we work together more the players understand more the mentality that is required and the demands and you can now see the standard of performance we have put in place. And then the results will come.

“The second half the only downside was we never took the chances we created but we were much better 11 v 10 than we were at the weekend.

“We spoke about that after Rangers. You have to really dominate possession and counter press and we did that really well in the second half.”

Celtic have won all four of their games over the festive period after losing consecutive league matches for the first time in a decade.

“I think you can see that it is getting better and improving,” Rodgers said.

“Those results against Kilmarnock and Hearts, it was about learning from those. I think you can see the difference in the team and how they are working.

“And sometimes you need that. To have success you need to have that bit of adversity. How the players have responded to that has been fantastic.

“Their mentality, their attitude, the speed, the tempo of the games is what we want as well with much more creativity. The second part of the season I am excited about.”

Olusanya was sent off after catching Joe Hart in the face with his studs with a high boot following a VAR review but the game already looked beyond St Mirren.

Manager Stephen Robinson said: “It was a long evening. You can’t start like that and win football matches. Effectively the game was dead after six minutes.

“The more you come out the more they can open you up, so the game plan goes out the window.

“Frustrating, because we spoke about getting done on our inside shoulders with Maeda’s runs, and for the third goal we also got done for dropping our runner.

“As well as Celtic showed a lot of quality, of course, we didn’t control that situation well enough.

“Then it’s compounded by the red card which makes it damage limitation whichever way you dress it up.”

Oh Hyeon-gyu capitalised on a rare start to hit a double as Celtic consolidated their position at the top of the cinch Premiership with a 4-1 victory over Hibernian at Parkhead.

Oh got the final touch on Celtic’s opener from a fifth-minute set-piece before hitting the fourth shortly before making way for Kyogo Furuhashi.

Matt O’Riley’s header and a Luis Palma penalty had extended Celtic’s lead in between the South Korean’s goals.

Substitute Christian Doidge netted a consolation for Hibs to give them some reward for Nick Montgomery’s attempts to build from the back and utilise his many attacking players.

Celtic manager Brendan Rodgers brought in Tomoki Iwata, Mikey Johnston and Oh, who had one start between them this season.

Iwata came into the holding midfield role for his first start under Rodgers, allowing Callum McGregor to push further forward. Johnston was making his first start since February 2022, after making three substitute appearances since his return from a loan spell at Portuguese side Vitoria Guimaraes.

The champions got an early settler when Cameron Carter-Vickers got on the end of Palma’s corner and hit a shot which skimmed off Oh’s leg and beat David Marshall.

Oh was on the end of several crosses without seriously threatening before Marshall parried McGregor’s 25-yard strike.

The second goal came in the 36th minute when O’Riley timed his run perfectly to head home Palma’s cross after the winger had turned Lewis Miller inside out.

There were more chances at either end before the break. Alistair Johnston and Carter-Vickers both almost converted balls across the face of goal while Joe Hart made a good stop from Elie Youan.

Nat Phillips replaced Carter-Vickers at half-time and Celtic went further ahead in the 51st minute when Palma sent Marshall the wrong way from the spot.

Referee John Beaton was initially unconvinced over Lewis Stevenson’s challenge on Alistair Johnston but he did not take long to change his mind after being called to the VAR monitor by Gavin Duncan.

Oh netted four minutes later when he got on the end of McGregor’s ball down the left channel, brushed off Will Fish and guided the ball into the far corner.

Youan hit the post with a deflected effort before the wide player set up substitute Doidge for a 72nd-minute tap-in with a return pass.

Australian winger Marco Tilio had come on in the 63rd minute for Celtic for his second appearance for the club. The Australian winger created a decent shooting chance for himself but shot weakly at Marshall from 20 yards.

Celtic came closer when Marshall stopped Palma’s free-kick and both Furuhashi and Iwata missed glorious late chances.

Celtic midfielder Matt O’Riley will keep focusing on his daily routines for self-improvement rather than be derailed by thoughts of Euro 2024 after making his Denmark debut in midweek.

The 23-year-old won his first cap in Monday’s 2-0 defeat against Northern Ireland at Windsor Park.

Kasper Hjulmand’s side had already won their group before the Belfast trip and O’Riley will keep trying to impress for Celtic with his international hopes firmly in the back of his mind.

“The first cap is obviously a good moment, albeit it wasn’t our best performance, but at the same time you are still playing for your country,” he said.

“It was a proud moment for me and my family also. My family were there, my mum and dad, girlfriend and agent/friend.

“It’s obviously a new experience, new team-mates, new players, that’s always challenging because it’s a new environment, new people, so it takes a bit of time to adapt naturally but I found it relatively easy just because they are really nice people.

“The first few days you are a little bit nervous, just getting into it, but after that you are fine.

“It’s not something I gave too much thought to, you are still just playing football at the end of the day. If I am playing with good players and playing under a good manager, it shouldn’t really be a problem to play well.

“And yeah, of course I was disappointed with the result and I was hard on myself after the game because you naturally are when you lose but I received some nice feedback regardless.

“I am obviously in the mix now so it’s about trying to keep improving.”

On the prospect of playing in Germany next summer, the former MK Dons midfielder said: “It was always a target anyway. It’s something I try not to think about too much on a regular basis, it’s more a case of daily processes here, boring day-to-day stuff, that usually helps get you to where you want to get to.

“It’s four or five months to the next camp so there is a lot of football to be played for your club before then and a lot of things can happen in terms of performances, so I will try my best.

“That’s what got me there in the first place and I will try to keep improving as a player.

“I feel good, feel strong physically and mentally, which is progress. I feel like I have improved a lot this season on various aspects.”

One of those aspects is goalscoring – O’Riley has six goals to his name ahead of Saturday’s visit of Motherwell, more than his total from last term.

When asked what had contributed to his figures, the former Fulham trainee said: “A clearer mind first and foremost, I am more open when I am on the pitch.

“Secondly just getting into the right positions to score and then taking a little bit of pressure off myself, not expecting myself to score every game, just going into trying to do my best for the team and naturally you get your outcomes.

“You have to go through experiences. I had to go through the phase where I didn’t score for a long time to know maybe then how to take pressure off myself the next time.

“For me the big thing that has helped the most is just being in the best frame of mind. That’s something I give a lot of attention to on a daily basis.

“I meditate a lot, I speak regularly with my friend/life coach who lives in India. I work a lot with him in terms of speaking about things that were maybe kept inside me for a long time.

“I might not have had the knowledge to understand how to speak about it.

“That has helped me loads, I feel more confident and open to speak to people in general.”

Matt O’Riley believes Celtic need to use Kyogo Furuhashi even more after the Japan striker scored his ninth goal of the season in the 6-0 thrashing of Aberdeen on Sunday.

The Hoops went into the game on the back of a 6-0 Champions League defeat by Atletico Madrid on Tuesday but they blew the Dons away starting with South Korean forward Yang Hyun-jun’s first goal for the league leaders in the ninth minute.

Furuhashi was more than grateful that O’Riley set him up for the second soon after to take his goal ratio for club and country so far this season to almost one in two games.

Winger Luis Palma scored a penalty in the 76th minute and the Hoops struck three times in 10 added minutes at the end of the game, with Celtic substitutes David Turnbull and Oh Hyeon-gyu, twice, notching as Brendan Rodgers’ men restored their eight-point lead over Rangers at the top of the table.

O’Riley said of “nice man” Furuhashi, who had to go off with a head knock in the second half: “Me and him have a really good relationship on the pitch and I think probably 70 percent of the assists I have for Celtic have been for him, and that shows how good he is to play with, and how easy is to play with him.

“His movement’s top class. I actually think we need to use his runs a little bit more because his movement’s so good.

“He deserves the ball to be given to him because he works hard to create the space for himself. We need to keep utilising him because he’s our best goalscorer and that would be helpful going forwards.”

O’Riley described the response to the mauling in Madrid which left them bottom of their Champions League table as “perfect”, and believes such a convincing domestic result had been on the cards.

He said: “I think a result like that was pending in the league, to be honest.

“We’ve put in enough good performances and it was time – with the utmost respect – that we gave someone a real doing.

“There were a lot of chances created and it could’ve been more. It was needed.

“I shanked one from about three yards, so was a questionable finish.

“But we were on it right from the start with our runs in behind. We let them know they were going to be in for a game right from the start and we maintained that level throughout.

“We tire teams out, the way we play. And I think when you are 3-0 down at Celtic Park and you have been running for 90 minutes and haven’t had much of the ball, naturally you are going to be tired.

“The spaces do open up and we had boys coming off the bench for the last half hour ready to fire. James (Forrest), and then Bull (David Turnbull) comes on and scores. I think having that strength in depth to come on and really push the fitness levels, it is hard for teams to live with.”
