Here are the top 10 current favourites for the position...
5. Frankie McAvoy - 8/1
A man from the previous regime, Frankie McAvoy was Alex Neil's former assistant and would provide a bit of continuity. He worked with Alex Neil at both Hamilton and Norwich City before joining PNE and has a chance to take the job already.
6. Grant McCann - 20/1
Currently the boss at Hull City who are top of League One, McCann last experience in the Championship was being relegated with the Tigers last season. May want to wait until the end of the campaign to see out the job with his current side.
7. Callum Davidson - 8/1
A legend around Deepdale, Callum Davidson spent seven years as the left back for the Lilywhites. He's progressed as a coach and currently has the top job at St Johnstone, winning the Scottish League Cup this season.
8. Neil Harris - 16/1
Helped Cardiff City into the play-offs this time last season, partly at PNE's expense. Started this campaign poorly and was sacked by the Bluebirds but did a decent job in his time in Wales and previously at Millwall.
