Alex Bruce has been told by Celtic stars that Callum McGregor is spearheading their march to a fourth consecutive domestic treble.

Speaking exclusively to Football Insider correspondent Russell Edge, the just-retired footballing son of Steve Bruce has played against McGregor and the all-conquering Hoops side.

Defender Bruce, 35, spent the last year of his career in the SPL at Kilmarnock before hanging up his boots at the end of January.

He is in no doubt about the importance of McGregor, 26, or how he is viewed from within the dressing room of the Scottish champions.

“Very important, he’s a clever player,” Bruce told Football Insider. “The Celtic lads that I’ve spoke to say that he’s one of the biggest players in terms of what he brings to the team.

“Makes clever runs into the box, chips in with goals, keeps the ball in tight areas, creates goals as well, can hit it with either foot on the edge of the box, he’s a real good player.

“It’ll be interesting to see if he ever gets that chance to go to the Premier League.”

McGregor has been linked with a move down south, including Leicester City, but signed a new five-year contract with his boyhood club last November.

Since graduating from the Celtic youth ranks, he has made 273 appearances for the club, scoring 48 goals and supplying 56 assists from various midfield roles.

Bruce’s verdict on McGregor came after he gave an emphatic thumbs-up for his teammate Odsonne Edouard and revealed he’d urged his Dad to sign him at Newcastle United.
