Simon Jordan has urged Martin O’Neill to come back swinging after the Celtic boss cast doubt over his future as manager.The Scottish champions endured a nightmare seven days as they were beaten by Old Firm rivals Rangers twice in that period.O’Neill has suffered three defeats in the space of seven daysGettyO’Neill‘s side lost 1-0 at Celtic Park to end their perfect start to the Scottish Premiership season, which followed a 3-0 defeat in the Scottish League Cup at Ibrox.To make matters worse, the Hoops also suffered a reverse at home against Hungarian side Ferencvaros in the Europa League on Thursday night.Celtic have now lost four matches in all competitions this season, as many as they did in 35 games under O’Neill last term.The 74-year-old was handed a one-year deal in June after guiding Celtic to a league and Scottish Cup double during his return for a second spell as caretaker manager in January.O’Neill’s bleak assessmentFollowing Celtic’s latest Old Firm defeat, O’Neill cast doubt over his future in the role and admitted he was considering whether he was the right man to lead the team.He told reporters: “I genuinely will reflect and see. “It’s a matter of whether I can help the team. If that’s the case – the manager’s supposed to be able to do that. I will have a look at that there this week. “I think that every single time that something crops up things don’t go so well, age plays a part, and you know what? They may well be right – you know I’m 110 in two years time. “So yeah, it might be time to wrap it up.”Jordan tells O’Neill to fight backFollowing O’Neill’s comments on his future, talkSPORT’s Jordan has insisted the Northern Irishman should have delivered a more defiant message in the wake of a difficult run of results.Ryan Naderi scored the only goal as Rangers beat Celtic for the second week in a rowGettyHe said on White and Jordan: “I’ve liked to see him being a bit spikier and a bit more robust, rather than sounding relatively defeated in that clip. Explaining how he would have reacted, the ex-Crystal Palace chairman said: “I certainly would have been wanting to say back to them, ‘This has happened, it will not happen again – I have to accept the fact this week, put aside the European game which I’m disappointed in as well, but losing twice to Rangers in a week does not happen at this football club I have to take responsibility for and it’s not happening again’. “I would have liked to have heard that.”With O’Neill previously a regular on talkSPORT’s White and Jordan show, Jordan admitted the press conference came as a shock to him.Highlighting Celtic’s reverse defeat in Sunday’s Old Firm – where away fans weren’t allowed at Celtic Park – the talkSPORT host claimed he will likely have been hurting.Jordan continued: “The fact that he’s talking about whether he can help the team and whether it’s his time – I find that slightly strange of Martin, but he’s having a reflective moment. O’Neill has admitted he is considering his future as Celtic managerGetty“He’s not enjoyed the discreditation of his side, because he did turn around and say during the course of last week, ‘We’ll see how they get on when they come back to a place where they haven’t got their fans to support them’.“So he won’t like that, he needs to get his shoulders back and his chest out.”‘Tough get going’O’Neill previously spent five years in charge of Celtic between 2000 and 2005, during which time he won seven trophies including three league titles and reached a UEFA Cup final.And Jordan urged O’Neill to remember his past achievements as he called on him to portray a more confident exterior going forward.He added: “He’s still the same man.“There’s nothing that happened in Martin’s life physically or mentally to change the difference between the guy that came in and got them centred on being a decent Celtic side to win the Scottish Premiership whatever that’s worth to us English [people] that watch a proper league. O’Neill won two trophies with Celtic in the 2025/26 seasonGetty“But he needs to regain that poise, because he’s Martin O’Neill and he’s better than the results as they stand at this moment in time, and he’s better than that interview.”Rounding off, Jordan urged O’Neill to stand firm in the face of adversity, insisting he accepted the challenges of his role when he took on the permanent role at Celtic Park.Jordan said: “He took the job knowing what the challenges were and he went into another season wanting to embrace it and he danced around playing a little quizzical Irishman with the media, and about how old he was and stuff. “But he took the job on, and now it’s tough. And when it gets tough, get going.”
