Former Republic of Ireland international Tony Cascarino has suggested that Celtic should contemplate bringing Robbie Keane to work alongside Martin O’Neill at some point, describing the veteran coach as the perfect mentor for a potential future head coach at Parkhead. The Hoops have placed their faith in a familiar figure for the time being but acknowledge the need to identify a long-term successor to their 74-year-old manager.

O’Neill, who guided Celtic to a league and cup double while serving as interim boss, had previously stepped in to stabilise the club following Brendan Rodgers’ departure in October 2025 and Wilfried Nancy’s brief eight-game stint, which lasted just 33 days. His steady leadership during that period culminated in both Scottish Premiership and domestic cup triumphs, making his subsequent permanent appointment unsurprising.

The Northern Irishman has signed a one-year deal that includes an option for a 12-month extension. Although other candidates were linked with the Glasgow giants, Celtic’s board have prioritised stability and continuity over taking another managerial risk in the immediate term.

Robbie Keane, who previously enjoyed a loan spell at Celtic Park during his playing days, was reportedly considered for a role at one stage. The former Republic of Ireland striker has been developing his coaching career with Maccabi Tel Aviv and Ferencvaros, where he has made notable strides.

Cascarino, speaking on behalf of Tonybet during their World Cup Card Collection campaign—which offers Irish participants a chance to win up to €100,000—told GOAL that he believes Keane could be a valuable addition to Celtic’s future plans. He said, “I hope so. I knew Robbie when he was a young lad, when I was playing for Ireland and he’d come up front alongside me.”

“Robbie’s been out there earning his stripes, as every aspiring coach must. Breaking into Premier League management is incredibly tough, with so many experienced names ahead in the queue. But I genuinely think Robbie and Celtic would make a great combination. I like the idea of Martin O’Neill being there to oversee someone like Robbie—and let’s be honest, Martin would support him rather than hinder him.”

Cascarino went on to draw a comparison with former Republic of Ireland manager Steve Staunton, who once worked alongside Sir Bobby Robson. “I remember when Steve got the job and had Bobby Robson with him for a short period. It was a pity because Bobby wasn’t well at that time. It would have been even better if he’d been in good health to help Steve more fully. Having that kind of experience above you is invaluable, especially when dealing with the board and people upstairs—it’s something that frustrates plenty of managers.”

Looking ahead, Cascarino believes Keane might pursue another opportunity in British football before being ready for a managerial post as significant as Celtic’s. The 46-year-old will likely seek further experience to strengthen his credentials, keeping himself active and prepared for future challenges.

If Keane’s coaching career continues to progress positively, there’s a strong possibility that his journey could bring him back to Scotland. In that scenario, O’Neill might remain involved at the club in a director’s capacity, offering invaluable guidance to those taking charge on the touchline.
