Martin O’Neill Provides Positive Update on Kieran Tierney's Recovery
Martin O’Neill has given Celtic supporters the update they wanted on Kieran Tierney – even if the defender will still be missing when the team walks out in Paisley on Saturday.
Tierney, 29, will sit out the meeting with St Mirren, but O’Neill revealed the left-back is recovering far quicker than first feared and is now on course for a return in the coming days rather than weeks.
At his Friday press conference, the Celtic manager painted a far brighter picture than the one that initially accompanied the injury.
“Yeah, so, Kieran is doing fine at this minute. Really fine,” O’Neill said. “I thought that he might be a wee bit longer, and he’s doing fine.”
Pressed on whether Tierney or fellow absentee Kasper Høgh might make a surprise appearance at the weekend, O’Neill was blunt.
“I would have thought it very, very unlikely for both of them,” he admitted.
The message was clear: no risks in Paisley, but genuine optimism just beyond it. If Tierney comes through the next phase of training without a setback, O’Neill expects him to be available either for the midweek fixture or the match that follows. Given the early concern over the extent of the problem, that represents a significant shift in mood inside Celtic Park.
A missing piece on the left
The urgency around Tierney’s return is not just sentimentality. Celtic look different with him in the side.
He gives them something no one else in the squad quite replicates: natural width from deep, relentless overlapping runs and the recovery speed to rescue situations when the full-back has bombed on. In O’Neill’s pressing system, that matters. One full-back is asked to step high, the other to tuck in and form a back three. Tierney reads that balance instinctively.
He can drive into open grass, drag markers into uncomfortable areas and clear the channel for the left winger to drift inside. Without him, Liam Scales and others can fill the shirt, but the pattern changes. Attacks lose a touch of tempo, and when Celtic turn the ball over, the back line can look more vulnerable.
Last season’s numbers back up the eye test. A reported 4.2 successful tackles per 90 minutes underline how often Tierney breaks up play and turns defence into attack. For a side that wants to squeeze high and suffocate opponents, that edge is priceless.
Squad depth buys Celtic time
O’Neill’s summer rebuild has given him room to breathe. Five loan signings arrived in the frantic final 48 hours of the window, swelling a squad that now has to cope with a domestic campaign and the demands of Europe.
That extra depth changes the calculation. Celtic no longer have to gamble on half-fit players just to get through the schedule. Tierney and Høgh can be managed, not rushed.
There is a cost, though. O’Neill has already had to navigate UEFA’s strict registration rules, confirming that three young players were left out of the Europa League squad because of the sheer volume of senior options. It is the kind of selection headache managers claim to want, but it still leaves talented prospects watching from the sidelines.
When Tierney does return, the left flank could look transformed again. His pace, his range of passing and his willingness to surge forward allow Celtic to be aggressive without tearing holes in their own back line. The shape breathes differently when he is there.
For now, St Mirren comes too early. The difference this time is that Celtic are counting down days, not dreading weeks. With Høgh still short of full availability and the fixtures stacking up, the timing of Tierney’s comeback may say plenty about how far O’Neill’s new-look squad can really go this season.
