CALLUM McGregor would have been surprised and disappointed had the offer of a contract extension not been forthcoming from Celtic given his considerable personal contribution to the success the Parkhead club enjoyed last season.

The midfielder established himself as an invaluable member of Brendan Rodgers’s side as they qualified for the Champions League, won the Ladbrokes Premiership, Betfred Cup and William Hill Scottish Cup and went undefeated domestically.

The goals he scored against Rangers in a 2-0 Scottish Cup semi-final triumph at Hampden and record 5-1 victory at Ibrox in the Premiership a week later were simply the highlights of what was an exceptional individual campaign.

Yet, the 24-year-old, who has pledged his future to the Glasgow club – which he grew up supporting in Easterhouse and then Springboig – until 2021, still welled up as he signed his new deal at Celtic Park earlier this week.

Returning to the room where Tommy Burns had offered him his first contract many years before brought memories of the club great and the important role he had played in helping him to realise his dream of becoming a professional footballer flooding back to him.

“When I signed into the pro-youth system, Brian Meehan was the head of youth, Mark Millar was the coach and Tommy Burns was overseeing it,” said McGregor.

“Tommy was a massive influence for me coming all the way through. He would be at first-team training during the day then come to supervise us at six o’clock. We would still be there at 10 o’clock practising free-kicks. He wouldn’t let us go home. He was just that kind of guy, he loved football dearly.

“When I signed the new contract the other day I signed it in the little room just off the boardroom. That was the first time I had been in there since the day I sat with Tommy and my parents to sign my first pro-youth contract at the age of 13.

“Because it was the first time I had been back in the room and it was a nice feeling, I texted my mum and mentioned it to her and she said it was nice to see how far I have come in the years since. It did feel emotional.

“It’s a proud moment for me to tie my future down at the club where I have spent the bulk of my career. To come through from the age of eight means something to me. There aren’t many left from the same era and it just shows you what you can do if you work hard and have the right support around you.”

Burns, the former Celtic player, manager and coach who passed away in 2008 from skin cancer, would be proud of how his protege has flourished during the last few years and of how he acquitted himself in the games against Rangers last season especially.

“It’s been a progression ever since I broke into the first team, step by step,” said McGregor. “But I probably think of last season and the game at Ibrox when I scored against Rangers was the moment when I thought: ‘You know what, that’s me here’. Everybody begins to give you respect as a first-team player.

“I have been here since I was eight years old. It is pretty much all I have known in terms of football.”

Brendan Rodgers, the manager who has been responsible for him since he broke into Ronny Deila’s team, has raised the point that Celtic supporters have no chants about McGregor while Kieran Tierney, another to have come through the ranks from an early age, is regularly lauded in songs from the stands. The player, though, is not perturbed by the relative lack of recognition.

“The fans are always on about Kieran,” he said. “But I am just happy to go under the radar. It doesn’t faze me.”
