Celtic will likely find themselves searching for a new manager at the end of the season, with Martin O'Neill's contract set to come to an end.
There is an option to extend the deal, but based on this season, it doesn't look likely an extension will be on the table. It's unclear whether Celtic have started their search just yet, but here we look at the latest favourites.
Shaun Maloney
The current Celtic number two is the favourite to take over as things stand, and this may be the bookmakers hedging their bets in case O'Neill is sacked during the season.
In terms of the long-term search for an O'Neill replacement, it would be a surprise if Celtic turned to Maloney. The Bhoys fans are not overly impressed with how the team is playing this season, and given Maloney is the main man behind the coaching, it doesn't bode well. Fans wouldn't be particularly impressed with this appointment.
Robbie Keane
While we are on that topic, the civil war between Celtic and the board would likely reach an all-time low point if Keane was appointed. Keane was linked with the job in the summer, and many fans revolted at the idea due to the Irishman's previous experience in Israel and the fact he did not walk away from his role there at a time when Israel began their UN-defined genocide of Palestine. Celtic fans haven't forgotten that.
Craig Bellamy
Bellamy could be a popular appointment. The Welshman spent time at Parkhead as a player and he was linked with a move away from the Wales job in the summer, when his former club Burnley came coaching.
The Wales job is the only senior job Bellamy has had, so there will be questions over his experience. The pros? Bellamy has a clear way of playing, an expansive and attacking brand of football. He is also the sort of character who will stand up to the board when it comes to recruitment.
Neil Lennon
Lennon has done well with Celtic previously, but fans are unlikely to be in love with the idea, given the change in playing style they want to see. Lennon talks sense on TV, when he covers Celtic, and he has suggested he would demand more of the board, but you never know how that will go in practice.
Kieran McKenna
The most attractive appointment but also the most ambitious. McKenna got Ipswich Town promoted to the Premier League for the second time in three years before walking away from the job.
He is taking a break from football aside from a UEFA advisory role. When he returns, McKenna could have Premier League options, so Celtic may find it hard to compete.
