Callum McGregor's Future at Celtic: From Player to Potential Manager

Callum McGregor has spent a decade dictating Celtic’s tempo from the centre of the pitch. Martin O’Neill now believes he could one day dictate everything.

The former Celtic manager has tipped the 33-year-old captain as a future boss at Parkhead, after McGregor quietly moved to end any doubt over his own plans by telling chief executive Michael Nicholson he is happy to stay with the Scottish champions. Amid the swirl of speculation about a lucrative move to Saudi Arabia, the club’s on-field leader chose the familiar glare of Glasgow over the desert gold.

O’Neill, who knows exactly what it takes to survive and thrive in that dugout, sees more than a metronomic midfielder. He sees a manager in waiting. The talks McGregor held with Nicholson over the summer were framed as a check on his long-term future. They now look like the opening chapter of a transition from captain to potential coach.

While McGregor settles his direction, Celtic’s recruitment department continues to grind through a complicated window.

Kieran Tierney

The homegrown left-back whose name still echoes around Celtic Park, has attracted interest from Osasuna. The Spanish club made an approach for the 29-year-old Scotland international, but Celtic have knocked it back. The message is clear: if Tierney is to move again, it will not be on the cheap and not on someone else’s terms.

Transfer Activity

On the wings, the story is one of bids rebuffed and negotiations stretched. Frosinone have rejected Celtic’s opening offer of around £6m for Fares Ghedjemis. The 23-year-old Algeria winger has also been linked with Rangers, adding a familiar edge to the chase. The Serie A side want to keep him, yet talks remain alive, the kind of slow-burn pursuit that can define a window.

The pursuit of Mika Baur has followed a similar pattern, but with sharper resistance. Celtic are preparing an improved, structured package worth around £5m for the 22-year-old Paderborn midfielder, who is pushing to make the move to Glasgow. However, a £4m bid has already been turned down, and head coach Ralf Kettemann has gone on record with NW Sport to say he expects Baur to stay. For now, Paderborn hold their ground, and Celtic must decide how far they are willing to go.

Haissem Hassan is another wide option on the radar, though Celtic are not the only ones circling. Real Oviedo have rejected an offer of approximately £6.2m from Lens for the 24-year-old winger, a stance that underlines how costly any serious move for the French-born talent will be. The market for attacking players is tight, and the prices reflect it.

Rangers’ Reshaping

Across the divide, Rangers’ own reshaping has hit a snag in one area and opened up in another.

Hull City are closing in on Tromso midfielder Jens Hjerto-Dahl, with the Championship club set to beat both Rangers and Cardiff City to the 20-year-old’s signature. Rangers have now withdrawn from the race, leaving Hull as clear front-runners. It is a rare defeat in the recruitment battle, and a reminder that English clubs with strong financial backing can still outmuscle Scottish sides for emerging talent.

Rangers have, however, explored another wide option. The Ibrox club have held discussions with Brighton & Hove Albion over Amario Cozier-Duberry. The 21-year-old winger is a coveted prospect, and Brighton have already rejected a £5m offer from Anderlecht. The Premier League club are in no rush to sell, and that stance immediately raises the bar for any Scottish suitor hoping to tempt them into a deal.

St Mirren and Lower Leagues

Elsewhere in Scotland, the market turns on quieter, but no less important, decisions.

St Mirren have found themselves at the centre of speculation over midfielder Killian Phillips. The 24-year-old has drawn attention, yet the club insist they have received no contact from any other side. For a team that relies on smart trading and timely sales, the coming weeks will reveal whether that calm holds or a serious bid finally lands.

In England’s lower leagues, Scottish interest is shaping another mini-saga. Notts County have expressed an interest in Northampton Town’s 25-year-old defensive midfielder Dean Campbell. He has attracted a cluster of League One clubs, with multiple reports on X confirming County’s place in the queue. For Campbell, it could be a pivotal move; for Northampton, another test of how they value a key squad piece.

Brighton, meanwhile, are again on the front foot in youth recruitment. They have agreed a fee with Manchester City for Scottish winger Mason Stephens. The 17-year-old is expected to sign a three-year contract, another example of Brighton’s relentless push to stockpile promising talent before it hits the mainstream.

At St Johnstone, optimism over a potential windfall has been checked by bad luck. The Perth club had hoped a summer move for former striker Adama Sidibeh, tipped for a £1.5m switch amid Championship interest, might trigger a significant sell-on bonus. Instead, Sidibeh has suffered a hamstring injury at Stockport County, a setback that could cool interest and delay any deal. For a club that relies heavily on such clauses, that injury lands like a financial blow as much as a sporting one.

Across Scotland, the stories differ but the theme is the same: decisions now will shape seasons, and in some cases, careers.

At Celtic, one decision already feels bigger than any single transfer. Callum McGregor has chosen to stay and keep leading from the pitch. The question now lingers in the background: how long before that leadership shifts from the centre circle to the technical area?
