Luke McCowan admits it feels like he has stepped inside a Parkhead time machine since working with the interim boss(Image: SNS Group)

Luke McCowan felt like he was in a magical Time Machine when Martin O’Neill walked back into Celtic.

But, while bombarded with questions from his dad about the boss, the midfielder reckons he’s been too scared himself to ask the gaffer about the trophy-laden old days at Parkhead.

McCowan reckons he could be travelling through three decades of Parkhead folklore when he steps into Lennoxtown.

At his side in the dressing room, he’s got stars of the Ange Postecoglou and Brendan Rodgers winning sides of the 2020s such as Jota, Cameron Carter-Vickers and Daizen Maeda.

Beside them are club heroes like Kieran Tierney, Callum McGregor and James Forrest who have been collecting medals since the 2010s under managers such as Neil Lennon, Ronny Deila as well as Rodgers in his first stint.

And leading from the front is the icon of Celtic’s 2000s in O’Neill with one of his charges from those days at his side in Shaun Maloney.

McCowan may not have started school when the boss took charge the first time, but he knew all about his hero status and subsequent exploits.

O’Neill’s Treble win in season one was just a third in Celtic’s history and it was the same number chalked-up in terms of European finals when he led famed charges such as Henrik Larsson to the Seville showpiece of the 2003 UEFA Cup.

McCowan gave an insight into what he felt when the iconic Parkhead boss returned and smiled: “I thought I was in a time machine.

“It’s kind of been like that, even Jota coming back as well and Kieran coming back. You’re kind of like: What the heck’s going on here?

“And, when he [O’Neill] came in, all I could think about was the UEFA Cup Final, what did he say in the dressing room? Lucky enough, I could just ask Shaun.

“But it’s been amazing. He’s got that aura and almost legendary status at this club, so fair play to him coming back and helping us out when we kind of needed it.”

McCowan undoubtedly has plenty of enquiries about the successful period O’Neill savoured during his first spell, the magical moments, the famous wins and the outstanding characters that he guided.

But questions are on hold for the time being as he said: “No, I’m too scared. I’m going to wait. It’s too serious at the moment. We’re all focusing on games, left, right and centre.

“There’ll be a time for that if they are still about for international break because I’m not going anywhere. If he’s about, he’ll get a few questions then.”

It’s not just McCowan that is looking for answers. His father is also keen to hear all about the magic of working with O’Neill and explained the excitement of his old man at the return.

He said: “He was buzzing. He kept pestering me with questions, but I’m just trying to play it cool. You’ve just got to kind of go: Aye, it’s alright, it’s fine.

“But we all know it’s nice to have the gaffer here and what he brought before. He’s obviously replicating that again.”

Much is made of O’Neill’s approach to the game. With a grounding from Brian Clough, simplicity has often been the key.

As opposed to being bogged down in stats and modern jargon, the manager was always feted for offering clear instruction and concise messaging.

However, to suggest he is merely old school would clearly be an insult to his footballing intelligence and his acumen.

As O’Neill said himself following the Euro defeat to Midtjylland last week that, although some things change in football, some stay exactly the same and it was his job to try and teach the squad on some important matters during his time at the helm.

McCowan is aware of what people say about O’Neill simplifying football and that managing these days would be a new experience for him, but he countered: “Yes, but there are still tactics within that. It’s not just, let’s just kick it long.

“Yes, he comes in with the message of ‘defenders do your job first, attackers score your goals,’ whatever it may be.

“That is the message that’s from him. But we’ve got so much tactics within that, that it’s not just him that comes in and it’s his one message.

“It’s everybody within the staff that’s at the club, all the boys, have got valued comments on how we’re playing, what we’re doing. The messages are clear.

“The gaffer brings that message, but there’s so many tactics within it.’

Whatever has been said between the combination of O’Neill and Maloney as well as their coaching staff in the past fortnight, it has brought three straight domestic wins with the defeat in Denmark the only setback in four matches.

Sunday’s 4-0 win over Kilmarnock was an impressive way to sign off for the international break and McCowan said: “Yeah, I think especially off the back of the European game, we knew we had to come to our home ground and put a good performance on first and that should lead to a positive result.”

O’Neill thinks he’ll find out this week if he is to continue in the job, but McCowan will be there long term and will keep working whilst team-mates are on international duty.

He said: “I’ll be in Lennoxtown. I’ll come on Tuesday, Wednesday and Thursday and then maybe give myself the weekend off. We’ll see how hard I’ve worked after Thursday!”
