Will Celtic make the right appointment in Ronny Deila's place?
Celtic are looking for a new manager after current boss Ronny Deila announced his intention to step down, via the club website.
With Rangers clinching promotion, it is more vital than ever they get this appointment right.
There is a real mix of names among the potential candidates, but will they end up playing straight into Rangers hands if they get it wrong?
Here are three names listed with the bookies which would leave Rangers fans smiling, and Celtic's more cautious.
Keane is listed as short as 8/1 with SkyBet, a price based on his big name and reputation rather than management success. He had a mixed spell with Sunderland which started well and ended poorly, while his time with Ipswich Town was a disaster. An assistant manager spell with Aston Villa looks even worse with hindsight, but he has put himself back in the frame by working with Martin O'Neill for Republic of Ireland. Keane has the passion required of a Celtic manager, but his managerial experience is woefully brief compared with bookies favourite David Moyes.
Owen Coyle has been discussed as a potential Celtic boss at previous openings, but his recent track record has been poor. Coyle, priced at 16/1 is blamed by many Bolton fans for setting them on their way to their current predicament, and his time at Wigan Athletic turned out just as poorly. There would be doubters from day one as to whether he is up to the job, which will make the task harder at any setback, while he also lacks the pulling power a bigger name may possess in the transfer market.
Alan Stubbs has a strong connection with Celtic from his playing days and knows just what it means to step out at Parkhead. Priced at 14/1, it is hard to see him sticking at Hibernian if the chance to manage Celtic comes around. Yet it is this spell with Hibs which will not worry Rangers fans, as they have seen off their challenge this season, and Mark Warburton will know what to expect in terms of tactical approach.
